There is nothing wrong in running regressions on aggregate data if one is interested in the aggregate model. For instance, for the governor of a state, it is correct to run regressions between police force on crime rate at the state level if one is interested in the policy implication of a rise in police force. However, an ecological fallacy would happen if a city council deduces the impact of an increase in police force in the crime rate at the city level from the correlation at the state level. Choosing to run aggregate or individual regressions to understand aggregate impacts on some policy depends on the following trade-off: aggregate regressions lose individual level data but individual regressions add strong modeling assumptions.

Bai, Ghysels and Wright (2010) examine the relationship between MIDAS regressions and Kalman filter state space models applied to mixed frequency data. In general, the latter involve a system of equations, whereas in contrast MIDAS regressions involve a (reduced form) single equation. As a consequence, MIDAS regressions might be less efficient, but also less prone to specification errors. In cases where the MIDAS regression is only an approximation, the approximation errors tend to be small.

A clear and certain understanding of major marine regressions has not yet been achieved; according to one hypothesis, regressions may be linked to a "slowdown in sea-floor spreading, leading to a generalized drop in sea level (as the mid-ocean ridges would take up less space)...."Courtillot, p. 141. In that view, major marine regressions are one aspect of a normal variation in rates of plate tectonic activity, which lead to major episodes of global volcanism like the Siberian Traps and the Deccan Traps, which in turn cause large extinction events.

Rayner, Foorman, Perfetti, Pesetsky, & Seidenberg (2001). There is considerable variability in fixations (the point at which a saccade jumps to) and saccades between readers and even for the same person reading a single passage of text. Skilled readers make regressions back to material already read about 15 percent of the time. The main difference between faster and slower readers is that the latter group consistently shows longer average fixation durations, shorter saccades, and more regressions.

Multivariate adaptive regression splines (MARS) is a non-parametric technique that builds flexible models by fitting piecewise linear regressions. Multivariate and adaptive regression spline approach deliberately overfits the model and then prunes to get to the optimal model. The algorithm is computationally very intensive, and in practice an upper limit on the number of basis functions is specified.

Spontaneous remission, also called spontaneous healing or spontaneous regression, is an unexpected improvement or cure from a disease that usually progresses. These terms are commonly used for unexpected transient or final improvements in cancer. Spontaneous remissions concern cancers of the haematopoietic system (blood cancer, e.g. leukemia), while spontaneous regressions concern palpable tumors; however, both terms are often used interchangeably.

Screenprint, data showing a tolerance level (threshold) of the wheat crop for soil salinity expressed in electric conductivity as ECe = 7.1 dS/m. As an alternative to regressions at both sides of the breakpoint (threshold), the method of partial regression can be used to find the longest possible horizontal stretch with insignificant regression coefficient, outside of which there is a definite slope with a significant regression coefficient. The alternative method can be used for segmented regressions of Type 3 and Type 4 when it is the intention to detect a tolerance level of the dependent variable for varying quantities of the independent, explanatory, variable (also called predictor).Free software for partial regression The attached figure concerns the same data as shown in the blue graph in the infobox at the top of this page.

USA 93: 136-140, 1996 SS1P has shown anti-tumor activity in a phase I trial when combined with chemotherapy. In a recently completed clinical trial, SS1P was combined with the immunosuppressive drugs cyclophospamide and pentostatin and produced remarkable major and sustained tumor regressions lasting up to 2 years in patients with advanced chemotherapy resistant mesothelioma.Hassan, R., Miller, A.C., Sharon, E., Thomas, A., Reynolds, J.C., Ling, A., Kreitman, R.J., Miettinen, M.M., Steinberg, S.M., Fowler, D.H., and Pastan, I.: Major cancer regressions in mesothelioma after treatment with an anti-mesothelin immunotoxin and immune suppression. Sci. Transl. Med. 5: 208ra147, 2013 Tumor shrinkage of this magnitude and duration has never before been observed in mesothelioma. Pastan’s current efforts are directed at improving the activity and usefulness of immunotoxins he has developed.

During the ice ages of the Pleistocene, a clear correlation existed between marine regressions and episodes of glaciation; as the balance shifts between the global cryosphere and hydrosphere, more of the planet's water in ice sheets means less in the oceans. At the height of the last ice age, at around 18,000 years before the present, the global sea level was 120 to 130 m (390-425 ft) lower than today. A cold spell around 6 million years ago was linked to an advance in glaciation, a marine regression, and the start of the Messinian salinity crisis in the Mediterranean basin. Some major regressions of the past, however, seem unrelated to glaciation episodes -- the regression that accompanied the mass extinction at the end of the Cretaceous Period being one example.

In least squares estimation problems, sometimes one or more regressors specified in the model are not observable. One way to circumvent this issue is to estimate or generate regressors from observable data.Pagan, A., 1984, “Econometric Issues in the Analysis of Regressions with Generated Regressors”, International Economic Review, 25 (1), 221-247. This generated regressor method is also applicable to unobserved instrumental variables.

In terms of wage regressions, the poor quality of schools for Black men had meant a lower value of the β coefficient on years of schooling for Black men than for White men. Thus, some of this lower β coefficient reflected a difference in the quality of education for Black workers which could have otherwise interpreted as an effect of discrimination.

These forecasts are generally used to predict events days or weeks out. Finally, statistical techniques utilize regressions and other statistical methods to create long-term projections that go out weeks and months at a time. These models allow scientists to visualize how a multitude of different variables interact with one another, and they illustrate one grand picture of how the Earth's climate interacts with itself.

Most CI systems allow the running of scripts after a build finishes. In most situations, it is possible to write a script to deploy the application to a live test server that everyone can look at. A further advance in this way of thinking is continuous deployment, which calls for the software to be deployed directly into production, often with additional automation to prevent defects or regressions.

Black argues that econometrics is filled with it in the forms of unobservables and mis-measurement. No matter how many variables one puts into a model, there are always more to add but can't (ones you can't observe) and the ones you have will always have error. This is how noise manifests in econometrics (as well as poor interpretation of regressions, such as assuming correlation means causation).

Luque approaches the problem with outliers by performing linear regressions over the set of data points (input, output). The algorithm deals with the data by allocating regions for noisy data. The scheme has the advantage of isolating noisy patterns which reduces the effect outliers have on the rule-generation system. The algorithm can come back later to understand if the isolated data sets influence the general data.

Engadget was positive in its review of the S4 Active, noting that the S4 Active had a more "high- end" appearance than the normal S4, had a more comfortable feel due to its thicker build, and that its buttons were "definitely superior" from a usability standpoint. However, regressions from the S4 were also noted, such as its lower display quality in comparison to the Super AMOLED.

The three- stage least squares estimator was introduced by . It can be seen as a special case of multi-equation GMM where the set of instrumental variables is common to all equations. If all regressors are in fact predetermined, then 3SLS reduces to seemingly unrelated regressions (SUR). Thus it may also be seen as a combination of two-stage least squares (2SLS) with SUR.

This group has been subjected to much research due to its hydrocarbon implications. This has allowed researchers to reconstruct paleoshorelines, and paleoflow directions. Multiple transgressions and regressions are recorded in the rocks from the upper Paleocene to the Eocene.

Immunostimulatory antibodies increase the activity of T lymphocytes through several mechanisms, including the blockade of inhibitory molecules that are present at the surface of T lymphocytes. These antibodies are often named "checkpoint inhibitors". Using them in cancer patients can lead to important and durable tumor regressions, and to improved survival of the patients. Clinical benefit from these treatments is positively correlated with the number of nonsynonymous mutations present in the tumors.

A variety of methods are used in econometrics to estimate models consisting of a single equation. The oldest and still the most commonly used is the ordinary least squares method used to estimate linear regressions. A variety of methods are available to estimate non-linear models. A particularly important class of non-linear models are those used to estimate relationships where the dependent variable is discrete, truncated or censored.

Evolutionary Catastrophes: The Science of Mass Extinction. Cambridge, Cambridge University Press, 1999; p. 89. A major regression could itself cause marine organisms in shallow seas to go extinct, but mass extinctions tend to involve both terrestrial and aquatic species, and it is harder to see how a marine regression could cause widespread extinctions of land animals. Regressions are, therefore, seen as correlates or symptoms of major extinctions, rather than primary causes.

Performance of VIX (left) compared to past volatility (right) as 30-day volatility predictors, for the period of Jan 1990-Sep 2009. Volatility is measured as the standard deviation of S&P500; one-day returns over a month's period. The blue lines indicate linear regressions, resulting in the correlation coefficients r shown. Note that VIX has virtually the same predictive power as past volatility, insofar as the shown correlation coefficients are nearly identical.

Linear regression is a standard tool from linear analysis. Hence, one of its main advantages is the widespread existence of standard tools for solving linear regressions efficiently. It has some educational value, since it highlights the basic property of Volterra series: linear combination of non-linear basis- functionals. For estimation, the order of the original should be known, since the Volterra basis functionals are not orthogonal, and thus estimation cannot be performed incrementally.

In two subsiding basins on both sides of today's chain, limestones, marls, foraminiferous sandstones, and sandstones with a benthic fauna were sedimented. The Eocene sedimentary successions along the French northern edge of the Pyrenees (in the North Pyrenean Zone) are fairly thin and full of facies changes. There, short-lived transgressions and regressions can be followed into the Languedoc.

The Maltese archipalego is linked to Sicily by an underwater plateau of depths of less than 100 m. During different marine regressions of the Mediterranean, Malta has been connected to Sicily by a surface isthmus by which animals have been able to cross, as evinced by the presence of island dwarfism (Maltese dwarf hippopotamus and dwarf elephant fossils),Courtin, J. as well as island gigantism (fossils of the Maltese Giant Dormouse, Leithia melitensis).

Sedimentary facies changes may indicate transgressions and regressions and are often easily identified, because of the unique conditions required to deposit each type of sediment. For instance, coarse-grained clastics like sand are usually deposited in nearshore, high-energy environments; fine-grained sediments however, such as silt and carbonate muds, are deposited farther offshore, in deep, low-energy waters.Monroe, James S., and Reed Wicander. The Changing Earth: Exploring Geology and Evolution, 2nd ed.

Belmont: West Publishing Company, 1997, pp. 112 - 113 Thus, a transgression reveals itself in the sedimentary column when there is a change from nearshore facies (such as sandstone) to offshore ones (such as marl), from the oldest to the youngest rocks. A regression will feature the opposite pattern, with offshore facies changing to nearshore ones. The strata represent regressions less clearly, as their upper layers are often marked by an erosional unconformity.

CDD was originally described by Austrian educator Theodor Heller (1869-1938) in 1908, 35 years before Leo Kanner and Hans Asperger described autism. Heller had previously used the name dementia infantilis for the syndrome. An apparent period of fairly normal development is often noted before a regression in skills or a series of regressions in skills. The age at which this regression can occur varies, but typically after 3 years of normal development.

Goolsby (1987), Smith (1988) It involves a saccade back to the previous note/chord (occasionally even back two notes/chords), followed by at least one returning saccade to the right, to regain lost ground. Weaver reported that leftward regressions run from 7% to a substantial 23% of all saccades in the sight-reading of keyboard music. Goolsby and Smith reported significant levels of leftward refixation across all skill-levels in the sight-reading of melodies.

Regression analysis is primarily used for two conceptually distinct purposes. First, regression analysis is widely used for prediction and forecasting, where its use has substantial overlap with the field of machine learning. Second, in some situations regression analysis can be used to infer causal relationships between the independent and dependent variables. Importantly, regressions by themselves only reveal relationships between a dependent variable and a collection of independent variables in a fixed dataset.

Outside of television, Schwartz was a licensed hypnotherapist with an office in Palm Springs. He also pursued in past life regressions, painted, and authored several non-fiction and fictional books. Schwartz was a longtime resident of Palm Springs, California for more than thirty years. He died from complications of surgery at Odyssey House in Palm Desert, California, on June 14, 2013, at the age of 89 (just nine days short of his 90th birthday).

The terrestrial stratigraphy of the Cenozoic is more difficult than that of marine deposits. The geologic timescale of the ICS is therefore based on marine fossils, that don't occur in terrestrial sediments. This makes the correlation of terrestrial deposits with the ICS timescale often difficult. Correlation is possible when marine deposits interfinger with terrestrial deposits (resulting from a series of transgressions and regressions of the sea during deposition), but this isn't the case everywhere.

Program One, the Projection Program, is based on the methodology of empirical econometric modeling. It uses regressions to derive mathematical relationships between key UI variables, and projects UI benefits, taxable wages, as well as workload variables on quarterly basis twelve years into the future. Program Two, the Financial Forecast Program, is based on the methodology of simulation modeling. It estimates Unemployment Trust Fund (UTF) income by simulating the workings of the State's taxation system.

The data may however be left-censored at a point higher than zero, with the risk of mis-specification. Both studies apply Probit and other models to check for robustness. Tobit models have also been applied in demand analysis to accommodate observations with zero expenditures on some goods. In a related application of tobit models, a system of nonlinear tobit regressions models has been used to jointly estimate a brand demand system with homoscedastic, heteroscedastic and generalized heteroscedastic variants.

Processes of eustasy lead to glacioeustatic sea level fluctuations due to changes of the water volume in the oceans and hence to regressions and transgressions of the shoreline. At times of maximum glacial extent during the last glacial period, the sea level was about lower compared to today. Eustatic sea level changes can also be caused by changes in the void volume of the oceans, either through sedimento-eustasy or tectono- eustasy.Ahnert, F (1996) – Einführung in die Geomorphologie.

Tests can be run at any point new code is introduced into a codebase to confirm no regressions within the existing test coverage are introduced. It can be integrated with Selenium and other browser emulators to generate screenshots of failures. Like other BDD frameworks, Behat scenarios are a series of Given, When, and Then steps that explain a business case. The definition of these steps exist within method annotations of a class that extends the BehatContext.

Infer is wired up to the code review system at Facebook. Its deployment model is to comment automatically on code modifications as they are submitted for review, where it reports potential regressions. It does this by incrementally analyzing code changes via a job on Facebook's continuous integration system which runs in its data centers. Infer also has a domain specific language for abstract syntax tree linting, based on ideas from Model Checking for Computation Tree Logic.

The user can start a bisection session with a specified range of revisions from which the revision control system proposes a revision to test, the user tells the system whether the revision tested as "good" or "bad", and the process repeats until the specific "bad" revision has been identified. Other revision control systems, such as Bazaar or Subversion, support bisection through plugins or external scripts. Phoronix Test Suite can do bisection automatically to find performance regressions.

Once the problem is fixed, the extracted test can be added to the test suite as a hedge against regressions of the problem. The third method of creating tests produces what are called generated tests. In this scenario, the user provides EiffelStudio AutoTest with the classes for which tests should be generated and some additional information used to control the test generation. The tool then begins calling routines in the target classes using randomized argument values.

Wealden Lake was a shallow freshwater to brackish lake which existed over the lands of what is now northern France and southern England during the Berriasian to Barremian ages of the Cretaceous epoch (approximately 145 to 125 mya). The sediments that deposited at the bottom of the lake over the course of its 20 ma existence form the Wealden Supergroup, a stratigraphic unit that paints a complex picture of climate change, marine transgressions and regressions and geological processes.

Belgian coast. A marine transgression is a geologic event during which sea level rises relative to the land and the shoreline moves toward higher ground, resulting in flooding. Transgressions can be caused either by the land sinking or the ocean basins filling with water (or decreasing in capacity). Transgressions and regressions may be caused by tectonic events such as orogenies, severe climate change such as ice ages or isostatic adjustments following removal of ice or sediment load.

Rory McIlroy PGA Tour received mixed reviews; although critics acknowledged the game's increased graphics quality and realism over previous installments in the franchise, the game was criticized primarily for its regressions over previous entries in the franchise, including a small number of available courses on launch, and the removal of various modes and features that had been present in previous PGA Tour games (however, additional courses, and some of these missing features, were added back in subsequent updates).

Noelle-Neumann herself tested the theory from the aggregate level. Using this approach, the change process is "observed by comparing the absolute share of people perceiving a majority climate with people willing to express their views over time." The second approach that has been used in Spiral of Silence research is conducting separate regressions for each panel survey wave. The drawback for this approach is that the individual change of climate and opinions perception is ignored.

A common, widespread cancer, non-small cell lung cancer is the cause of death in more people than breast, colorectal, and prostate cancer together. This is strong motivation to perform research on tyrosine kinase inhibitors as potential targets in cancer treatment. Gefitinib, functioning as an epidermal growth factor receptor tyrosine kinase inhibitor, improved symptoms related to non- small cell lung cancer and resulted in radiographic tumor regressions. This is an example of the efficacy of such an inhibitor.

Methods for estimating this exponent from data can use type-2 regressions, such as major axis regression or reduced major axis regression, as these account for the variation in both variables, contrary to least squares regression, which does not account for error variance in the independent variable (e.g., log body mass). Other methods include measurement-error models and a particular kind of principal component analysis. Allometry often studies shape differences in terms of ratios of the objects' dimensions.

This is usually not a problem for stock trading since stocks have weak time-series autocorrelation in daily and weekly holding periods, but autocorrelation is stronger over long horizons. This means Fama MacBeth regressions may be inappropriate to use in many corporate finance settings where project holding periods tend to be long. For alternative methods of correcting standard errors for time series and cross-sectional correlation in the error term look into double clustering by firm and year.

Technical analysis employs models and trading rules based on price and volume transformations, such as the relative strength index, moving averages, regressions, inter-market and intra-market price correlations, business cycles, stock market cycles or, classically, through recognition of chart patterns. Technical analysis stands in contrast to the fundamental analysis approach to security and stock analysis. In the fundamental equation M = P/E technical analysis is the examination of M (multiple). Multiple encompasses the psychology generally abounding, i.e.

Fifth edition; Thomson Brooks/Cole, 2005; p. 162. Evidence of marine regressions and transgressions occurs throughout the fossil record, and these fluctuations are thought to have caused or contributed to several mass extinctions, among them the Permian-Triassic extinction event (250 million years ago) and Cretaceous–Paleogene extinction event (66 Ma). At the time of the Permian-Triassic extinction, the largest extinction event in the Earth's history, global sea level fell 250 m (820 ft).Courtillot, Vincent.

Methods particularly useful in analysis of variance, and in constructing simultaneous confidence bands for regressions involving basis functions are the Scheffé method and, if the researcher has in mind only pairwise comparisons, the Tukey method. The use of Benjamini and Hochberg's false discovery rate is a more sophisticated approach that has become a popular method for control of multiple hypothesis tests. When neither approach is practical, one can make a clear distinction between data analyses that are confirmatory and analyses that are exploratory.

Grodsky and Pager also calculated wage differences, and found blacks to make $3.65 less per hour than whites in the private sector and $2.85 less in the public sector. Using statistical regressions, they found that human capital, region, and marital status account for 55 percent of the wage gap difference. An additional 20 percent of the wage gap was attributed to differences in occupational distributions between blacks and whites. Thus, 25 percent of the wage gap was unaccounted for by their model.

These are both idealized scenarios; in practice identifying transgression or regressions can be more complicated. For instance, a regression may be indicated by a change from carbonates to shale only, or a transgression from sandstone to shale, and so on. Lateral changes in facies are also important; a well-marked transgression sequence in an area where an epeiric sea was deep may be only partial farther away, where the water was shallow. One should consider such factors when interpreting a specific sedimentary column.

Selected academic research papers show how this technique has developed. Banbura, Giannone and Reichlin (2011) and Marta Banbura, Domenico Giannone, Michele Modugno & Lucrezia Reichlin (2013) provide surveys of the basic methods and more recent refinements. Nowcasting methods based on social media content (such as Twitter) have been developed to estimate hidden sentiment such as the 'mood' of a population or the presence of a flu epidemic. A simple-to-implement, regression-based approach to nowcasting involves mixed-data sampling or MIDAS regressions.

This distinction has become the source of a lot of bugs, and performance problems. EXA was introduced as a stopgap measure, to provide better integration with XRender than XAA did, improving the X.Org Server 2D performance. In practice, while this proved quite advantageous in some respects, it also exhibited a number of corner cases and regressions. The solution was to move to hardware acceleration with OpenGL for both 2D and 3D graphics with 2D graphics becoming just a subset of 3D rendering.

Cumulative Distribution Function of Hyperbolastic Type I, Logistic, and Hyperbolastic Type II PDF of H1, Logistic, and H2 Hyperbolastic regressions are statistical models that utilize standard hyperbolatic functions to model a dichotomous outcome variable. The purpose of binary regression is to predict a binary outcome (dependent) variable using a set of explanatory (independent) variables. Binary regression is routinely used in many areas including medical, public health, dental, and biomedical sciences. Binary regression analysis was used to predict endoscopic lesions in iron deficiency anemia.

Ghysels' most recent research focuses on Mixed data sampling (MIDAS) regression models and filtering methods with applications in finance and other fields. He has also worked on diverse topics such as seasonality in economic times series, machine learning and AI applications in finance, quantum computing applications in finance, among many other topics. Mixed data sampling or MIDAS regressions are econometric regression models can be viewed in some cases as substitutes for the Kalman filter when applied in the context of mixed frequency data.

The Cp statistic is often used as a stopping rule for various forms of stepwise regression. Mallows proposed the statistic as a criterion for selecting among many alternative subset regressions. Under a model not suffering from appreciable lack of fit (bias), Cp has expectation nearly equal to P; otherwise the expectation is roughly P plus a positive bias term. Nevertheless, even though it has expectation greater than or equal to P, there is nothing to prevent Cp < P or even Cp < 0 in extreme cases.

AGESA became particularly relevant with the AM4 platform, which AMD designed for futureproofing, and as of May 2019 has served as the base for three different generations of CPUs based on its Zen architecture. For each of these generations, a new branch of AGESA code has been released. AGESA versioning often runs separately for each of these three releases, so numbering regressions are bound to happen when going from one generation to the next. The first version, named "Summit PI", launched in February 2017.

It has also been used to test assumptions in spatial economics. The Uniform Standards of Professional Appraisal Practice, or USPAP, provides for mass appraisal standards to govern the use of hedonic regressions and other automated valuation models when used for real estate appraisal. Appraisal methodology treats the hedonic regression as essentially a statistically robust form of the sales comparison approach.John A. Kilpatrick, Real Estate Issues in Class Certification Hedonic models are commonly used in tax assessment, litigation, academic studies, and other mass appraisal projects.

Adoptive transfer involves either collecting from patients intratumoral or blood T cells, stimulate them in vitro against antigens present in the tumors and reinfuse them in large number into the patients, or using gene-modified T cells that recognize a tumor antigen. Important tumor regressions were observed in patients treated with IL-2 and very large numbers (≥1010) of expanded TILs (tumor-infiltrating lymphocytes).Rosenberg S. A., Spiess P., Lafrenière R. 1986. " A new approach to the adoptive immunotherapy of cancer with tumor-infiltrating lymphocytes ". Science.

If the Fisher information matrix is positive definite for all , then the corresponding statistical model is said to be regular; otherwise, the statistical model is said to be singular.. Examples of singular statistical models include the following: normal mixtures, binomial mixtures, multinomial mixtures, Bayesian networks, neural networks, radial basis functions, hidden Markov models, stochastic context-free grammars, reduced rank regressions, Boltzmann machines. In machine learning, if a statistical model is devised so that it extracts hidden structure from a random phenomenon, then it naturally becomes singular.

Allometric molar size regressions were used to calculate an estimated weight range of 600-900 g for C. browni. Both upper and lower canines were observed to be relatively large and long compared to the adjacent spatulate, and vertically placed incisors which are all features of modern anthropoids. The size of the olfactory bulb was measured as 4–5 mm long and 4 mm wide from specimen DPC 11434, a piece of fragmented frontal bone, using a latex mold of the outline of the imprinted braincase.

The Ordovician saw the highest sea levels of the Paleozoic, and the low relief of the continents led to many shelf deposits being formed under hundreds of metres of water. The sea level rose more or less continuously throughout the Early Ordovician, leveling off somewhat during the middle of the period. Locally, some regressions occurred, but sea level rise continued in the beginning of the Late Ordovician. Sea levels fell steadily in accord with the cooling temperatures for ~30 million years leading up to the Hirnantian glaciation.

Paul Newbold (12 August 1945 – 18 November 2016) was a British economist known for his contributions to econometrics and time series analysis. His most famous contribution was a 1974 paper co-authored with Clive Granger which introduced the concept of spurious regressions. Newbold earned his B.Sc. from London School of Economics and his Ph.D. under supervision of George E. P. Box at University of Wisconsin–Madison. He later was a professor most notably at the University of Illinois at Urbana–Champaign and the University of Nottingham.

The Mesilla Valley Shale is a geologic formation in southern New Mexico, northern Chihuahua, and far west Texas.Kappus and Lucas 2020 It preserves fossils dating back to the Albian age of the early Cretaceous period.Bose 1906Strain 1976 The formation is particularly well exposed at Cerro de Cristo Rey, where it is part of a thick sequence of uplifted Cretaceous beds that record transgressions (advances of the sea onto land) and regressions (retreats of the sea from the land) of the Western Interior Seaway during the mid-Cretaceous.

The first year of life is a time of substantial change in the development of both the human brain physical and motor development. During this a time, which is about 0-12 months, the baby's brain essentially doubles in size. However, an infant goes through several sleep regressions starting at 1 week, which can occur weekly or fortnightly, until 8 years of age. The sleep-wake cycle is a daily sleep pattern consisting of 16 hours of daytime wakefulness and 8 hours of night-time sleep.

Regressions were also noted, such as a lack of practice modes beyond Freestyle Solo tutorials, the shallowness of character customization, and the removal of online multiplayer. The soundtrack was also described as "underwhelming", albeit acknowledging several "seriously inspired choices", such as The Protomen. NPD Group reported that Rock Band 4 was the tenth best selling game for October 2015 based on units, while accounting for price, was the fourth best selling game. Analyst Michael Pachter estimated revenue from Rock Band 4 sales were about $100 million in early 2016.

The process of locating the changeset that introduced a specific regression was described as "source change isolation" in 1997 by Brian Ness and Viet Ngo of Cray Research. Regression testing was performed on Cray's compilers in editions comprising one or more changesets. Editions with known regressions could not be validated until developers addressed the problem. Source change isolation narrowed the cause to a single changeset that could then be excluded from editions, unblocking them with respect to this problem, while the author of the change worked on a fix.

These observations have prompted several clinical studies of infusing pathogen- or tumor-specific T cells into lymphodepleted patients. A group at the National Cancer Institute demonstrated remarkable efficacy by infusing melanoma-specific T cells (obtained by growing tumor-infiltrating T cells ex vivo) into melanoma patients treated with lymphodepleting chemotherapy. In a series of studies (to 2005) of this approach, up to 70% of treated patients were shown to have regressions of their tumors, many of which had been considerable in size and refractory to other therapies.Dudley ME, Wunderlich JR, Yang JC, et al.

Someone unfamiliar with the program being patched may install a patch using a patch utility created by another person who is the Admin. Even when the source code is available, patching makes possible the installation of small changes to the object program without the need to recompile or reassemble. For minor changes to software, it is often easier and more economical to distribute patches to users rather than redistributing a newly recompiled or reassembled program. Although meant to fix problems, poorly designed patches can sometimes introduce new problems (see software regressions).

In strife-torn Kashmir, a tomb called Rozabal holds the key to a riddle that arises in Jerusalem and gets answered at Vaishno Devi. An American priest,Father Vincent Sinclair has disturbing visions of people familiar to him, except that they seem to exist in other ages. Induced into past-life regressions, he moves to India to piece together the violent images. Shadowing his every move is the Crux Decussata Permuta, a clandestine secret society which would rather wipe out creation than allow an ancient secret from being disclosed.

The Chow test, proposed by econometrician Gregory Chow in 1960, is a test of whether the true coefficients in two linear regressions on different data sets are equal. In econometrics, it is most commonly used in time series analysis to test for the presence of a structural break at a period which can be assumed to be known a priori (for instance, a major historical event such as a war). In program evaluation, the Chow test is often used to determine whether the independent variables have different impacts on different subgroups of the population.

In statistics, the Durbin–Watson statistic is a test statistic used to detect the presence of autocorrelation at lag 1 in the residuals (prediction errors) from a regression analysis. It is named after James Durbin and Geoffrey Watson. The small sample distribution of this ratio was derived by John von Neumann (von Neumann, 1941). Durbin and Watson (1950, 1951) applied this statistic to the residuals from least squares regressions, and developed bounds tests for the null hypothesis that the errors are serially uncorrelated against the alternative that they follow a first order autoregressive process.

Application of the model involves repeated regressions over overlapping windows to compute an alpha and vector of betas for each, resulting in a statistical picture of a manager's style. Since 1992, this computation has been a feature of mutual fund analysis software produced by companies such as LIPPER, MPI, Zephyr Associates, and Morningstar. The exposures calculated by RBSA software can provide various pictures of a fund's evolution, both in isolation and in comparison to similar strategies. This analysis is usually done to better understand a fund over an explicitly chosen period of time.

Several software engineers, such as Joel Spolsky have warned against total rewrites, especially under schedule constraints or competitive pressures. While developers may initially welcome the chance to correct historical design mistakes, a rewrite also discards those parts of the design that work as required. A rewrite commits the development team to deliver not just new features, but all those that exist in the previous code, while potentially introducing new bugs or regressions of previously fixed bugs. A rewrite also interferes with the tracking of unfixed bugs in the old version.

In May 2020, an update was released to allow imports from Google Play Music, including purchased music, playlists, cloud libraries, and recommendations. The service still contains regressions over Google Play Music, including no online music store functionality (cannot purchase songs), and a YouTube Music Premium subscription being required in order to cast cloud library speakers to Google Home smart speakers. Google stated that they planned to address this and other "gaps" in features between the services before Play Music is shut down. A "pre-save" feature for upcoming releases was added in May 2020.

Harder had long been a strong advocate of extraterrestrial origins for UFOs, or the Extraterrestrial hypothesis. He also firmly believed that the subject has been covered up by the U.S. government, which he thought was extremely worried about what is happening. One of his more controversial statements, based primarily on hypnotic regressions on alleged alien abductees, is that there is a “Galactic Federation” of aliens similar to our United Nations. There are perhaps as many as 57 alien species in this Federation (a number, he says, which frequently pops up in abductee recollections).

This can be illustrated by considering a sentence such as: While Mary was mending the old grandfather clock struck twelve The words old grandfather clock may initially be attached as the direct object of the verb mending. The missing comma encourages this error. The fact that the attachment is incorrect becomes apparent when the word struck is encountered. The reader needs to re-analyse the sentence and there is ample experimental evidence that this process of re- analysis may be associated with re-inspecting eye movements (sometimes called "regressions").

Proper investigation of nitrite concentration changes and effects requires accurate quantification of nitrite levels The Weighted Regressions on Time, Discharge, and Season (WRTDS) method is used to estimate the concentration. The following equation provides the estimate: \ln(c)=\beta_0+\beta_1t+\beta_2ln(Q)+\beta_3sin(2\pi t)+\beta_4cos(2\pi t)+\varepsilon (1) where c is the nitrate concentration, \beta_0, \beta_1.\beta_2, \beta_3, and \beta_4 are fitted coefficients, t is time, Q is mean daily streamflow, and \varepsilon is the unexpected variability from other sources. This calibration curve is generated every day and compared to the one for the previous day.

Parents were told to expect developmental regressions in child survivors of the flood, especially those who lost their homes. Even in adults, the stress of applying for services and managing daily activities under catastrophic conditions, along with the summer heat and number of people needing the same things, was expected to exacerbate pre-existing anxiety, depression, or family conflict. The physical and emotional stress of cleaning out flooded homes was only part of the trouble, as parents needed to manage all of this while still caring for children who were home on summer vacation. Longterm consequences were expected as well.

In theory, 90% of extant funds could truthfully claim to have performance in the first quartile of their peers, if the peer group includes funds that have closed. In 1996, Elton, Gruber, and Blake showed that survivorship bias is larger in the small-fund sector than in large mutual funds (presumably because small funds have a high probability of folding). In this paper the researchers eliminate survivorship bias by following the returns on all funds extant at the end of 1976. They show that other researchers have drawn spurious conclusions by failing to include the bias in regressions on fund performance.

Regressions' sound is a complex and dense mixture of grindcore and doom metal with experimental leanings that touch on drone, noise and ambient music. In describing the band's sound, Philip Montoro of the Chicago Reader said "the music this Philadelphia four-piece plays is a kind of metal the way Lost Highway is a kind of movie. It's an elastic tissue of creepy electronic noise and barely human screaming, impregnated with patches of riff-salad grind and hypercube mathcore." The opener "Allotriophagy" is the lengthiest track on the album at nineteen minutes and twenty-three seconds.

These values are calculated dependent on T (length of the balanced panel—time periods the individuals were surveyed), K (number of regressors) and N (number of individuals in the panel). This test statistic can also be used for testing the null hypothesis of a unit root against stationary alternatives in fixed effects models using another set of bounds (Tables V and VI) tabulated by Alok Bhargava et al. (1982). A version of the statistic suitable for unbalanced panel data is given by Baltagi and Wu (1999).d1 in formula 16 in Baltagi/Wu (1999), Unequally spaced panel data regressions with AR(1) disturbances.

Hierarchical linear models (or multilevel regression) organizes the data into a hierarchy of regressions, for example where A is regressed on B, and B is regressed on C. It is often used where the variables of interest have a natural hierarchical structure such as in educational statistics, where students are nested in classrooms, classrooms are nested in schools, and schools are nested in some administrative grouping, such as a school district. The response variable might be a measure of student achievement such as a test score, and different covariates would be collected at the classroom, school, and school district levels.

The key reason for studentizing is that, in regression analysis of a multivariate distribution, the variances of the residuals at different input variable values may differ, even if the variances of the errors at these different input variable values are equal. The issue is the difference between errors and residuals in statistics, particularly the behavior of residuals in regressions. Consider the simple linear regression model : Y = \alpha_0 + \alpha_1 X + \varepsilon. \, Given a random sample (Xi, Yi), i = 1, ..., n, each pair (Xi, Yi) satisfies : Y_i = \alpha_0 + \alpha_1 X_i + \varepsilon_i,\, where the errors \varepsilon_i, are independent and all have the same variance \sigma^2.

With the formation of the supercontinent Pangea, the area became more arid in the Permian into the Triassic. Shallow water carbonates and evaporites belonging to the Khuff Formation deposited during a marine transgression, with microcrystalline dolomite, limestone and anhydrite up to thick and recording five marine regressions. With the westward uplifting of the region, it was succeeded by the Sudair Formation (dolomite, argillaceous limestone, shale and anhydrite) and the Gulailh and Jilh formations (offshore and on-shore in Abu Dhabi respectively). A full scale marine regression is recorded in the clastic lacustrine sandstones and limestones of the Minjur Formation.

This bay would have been subjected to enlargement and contraction brought about by transgressions and regressions driven by the 40,000-year Milankovitch cycles. The sediment in the outcrops mainly consists of coarse-grained and shelly sands that were deposited in sand waves (megaripples) that migrated parallel to the shore in a south-westward direction. The most common fossils are bivalves and gastropods that were often worn by the abrasive environment. The most extensive exposure is found at Bawdsey Cliff, which is designated a Site of Special Scientific Interest (SSSI); here a width of around of Crag is exposed.

The basal Hettangian-Sinemurian sequence is fully transgressive over basement rocks or Permo-Triassic sediments. At that time, the first open-marine sediments (yet rather poor in fossils) were being deposited in the Aquitaine Basin. The Lias Transgression, as it is also called, started to encroach on the entire Aquitaine during the Sinemurian, characterised by calcareous-dolomitic, partially oolitic sediments. Despite smaller regressions during the Pliensbachian towards the end of the Lias and at the beginning of the Dogger the sea had onlapped the basement rocks of the Massif Central and the western Vendée (reaching today's limits) by 30 km.

More generally, the expected value of a function of a random variable is the probability-weighted average of the values the function takes on for each possible value of the random variable. In regressions in which the dependent variable is assumed to be affected by both current and lagged (past) values of the independent variable, a distributed lag function is estimated, this function being a weighted average of the current and various lagged independent variable values. Similarly, a moving average model specifies an evolving variable as a weighted average of current and various lagged values of a random variable.

In 1983, Borch-Jacobsen participated in a meeting on the subject of hypnosis at the Hôpital Fernand-Widal where he joined such other as Léon Chertok, René Girard and François Roustang in the discussion of hypnosis. The following year, he published with Éric Michaud and Jean-Luc Nancy, Hypnoses. In this book, the authors consider the whole history of therapeutic hypnosis, the psychological or sociological theory becoming suspect to dangerous regressions from intellectual, ethical and political ideas. On 21 January 1985, he presented a conference paper entitled "L'hypnose dans la psychanalyse" ("Hypnosis in psychoanalysis") to the Society of Psychosomatic Medicine.

The ultimate success of Cristofori's invention occurred only in the 1760s, when the invention of cheaper square pianos, along with generally greater prosperity, made it possible for many people to acquire one. Subsequent technological developments in the piano were often mere "re-inventions" of Cristofori's work; in the early years, there were perhaps as many regressions as advances.Vogel (2003:11) notes several aspects of the modern piano action that were already employed by Cristofori ("moveable jack, single escapement, intermediate level, back check, upper damper"), citing them as "visible proof of Cristofori's genius" and observing that a number of these parts were "re-invented" during the evolution of the piano.

A relative change of the sea level leads to regressions or transgressions and eventually forms another terrace (marine-cut terrace) at a different altitude while notches in the cliff face indicate short stillstands. It is believed that the terrace gradient increases with tidal range and decreases with rock resistance. In addition, the relationship between terrace width and the strength of the rock is inverse, and higher rates of uplift and subsidence as well as a higher slope of the hinterland increases the number of terraces formed during a certain time. Furthermore, shore platforms are formed by denudation and marine-built terraces arise from accumulations of materials removed by shore erosion.

WWW 2001: 285-295 predicts the ratings on one item based on the ratings on another item, typically using linear regression (f(x)=ax+b). Hence, if there are 1,000 items, there could be up to 1,000,000 linear regressions to be learned, and so, up to 2,000,000 regressors. This approach may suffer from severe overfitting unless we select only the pairs of items for which several users have rated both items. A better alternative may be to learn a simpler predictor such as f(x)=x+b: experiments show that this simpler predictor (called Slope One) sometimes outperforms linear regression while having half the number of regressors.

For cervical carcinoma patients, long antigenic peptides derived from HPV proteins were used in cancer vaccines. It was shown that relative to the corresponding 9 amino acid peptides these peptides of 30-40 amino acids were better incorporated and presented by dendritic cells, leading to improved immunogenicity. Tumoral regressions were observed in initial stages of the disease.Kenter G. G., Welters M. J., Valentijn A. R., Lowik M. J., Berends-van der Meer D. M., Vloon A. P., Essahsah F., Fathers L.

In linear panel analysis, it can be desirable to estimate the magnitude of the fixed effects, as they provide measures of the unobserved components. For instance, in wage equation regressions, Fixed Effects capture ability measures that are constant over time, such as motivation. Chamberlain's approach to unobserved effects models is a way of estimating the linear unobserved effects, under Fixed Effect (rather than random effects) assumptions, in the following unobserved effects model :y_{it} = x_{it} b + c_i + u_{it} where ci is the unobserved effect and xit contains only time-varying explanatory variables.Wooldridge, J. (2002): Econometric Analysis of Cross Section and Panel Data, MIT Press, Cambridge, Mass.

However, the statistical assumptions employed in the econometric analysis make the assumption that all cross-sectional observations come from one statistical distribution that is the same for all cross-sectional observations. This tends to be the Achilles heel of virtually all cross-sectional analyses. If this homogeneous assumption is false, then cross-sectional observations are being drawn from different populations. While one can use estimation techniques such as fixed-effects to control for different population means, co-variances can also differ across populations (meaning behavior differs across populations) and the only way one can control for this aspect is to run regressions on each population separately.

The first to introduce and analyse the concept of spurious—or nonsense—regression was Udny Yule in 1926. Before the 1980s, many economists used linear regressions on non-stationary time series data, which Nobel laureate Clive Granger and Paul Newbold showed to be a dangerous approach that could produce spurious correlation, since standard detrending techniques can result in data that are still non-stationary. Granger's 1987 paper with Robert Engle formalized the cointegrating vector approach, and coined the term. For integrated processes, Granger and Newbold showed that de-trending does not work to eliminate the problem of spurious correlation, and that the superior alternative is to check for co-integration.

Critics were divided on certain aspects of its design, such as its rear button layout, and its plastic chassis—which was panned for closely resembling recent Samsung Galaxy products and being a regression from the glass-based chassis of the Optimus G. Similarly, while its software and user interface was praised for its usability and large number of customization options, some reviewers felt that the software suffered from feature creep and contained notable usability regressions in comparison to "stock" Android. Sales of the G2 exceeded LG's estimates; in late-December 2013, a Korean news agency reported that at least 3 million units of the G2 had been sold worldwide.

The key to the PTAAGMB model is the glacier’s area-altitude distribution, which is simply the glacier’s surface area as a function of elevation. The AA profile is a unique feature of a glacier that has been shaped by thousands of years of erosion of the bedrock underlying the glacier. Thus, the area altitude distribution has embedded within it the past climate history that has formed the glacier. The PTAAGMB model uses daily values of such balance variables as snowline altitude, zero balance altitude, glacier balance, balance flux and the accumulation area ratio are correlated throughout the ablation season using two-degree polynomial regressions to obtain the lowest fitting error.

Nurturing Our Humanity: How Domination and Partnership Shape Our Brains, Lives, and Future by Riane Eisler and Douglas Fry combines Eisler's partnership-domination social scale with extensive evidence from neuroscience and other fields. It shows that, contrary to popular beliefs about "selfish genes" driving human behavior, how people think and feel is heavily influenced by whether they grow up in partnership or domination oriented environments. It also documents that in reality humans in the course of evolution developed a propensity for empathy, caring, and creativity, which is, however, inhibited in domination systems. It further points to interventions that can accelerate the contemporary movement toward partnership and prevent further regressions to domination.

Letole, Rene, et al., "Uzboy and the Aral regressions: A hydrological approach", Quaternary International, March 2007 A riverine civilization existed along the banks of the river from at least the 5th century BC until the 17th century AD, when the water which had fed the Uzboy abruptly stopped flowing out of the main course of the Amudarya. The Uzboy dried up, and the tribes which had inhabited the river's banks were abruptly dispersed, the survivors becoming nomadic desert dwellers.Kapuściński, Ryszard, "Imperium", pp 65–69 In the early 1950s, construction work started to build a major irrigation canal roughly along the river bed of the former Uzboy.

While doing fish research at Scripps, Keys would use statistical regressions to estimate the weight of fish from their length, at that time a pioneering use of biostatistics. Once in Copenhagen (1931), he continued to study fish physiology and developed techniques for gill perfusion that provided evidence that fish regulated their sodium by controlling chloride excretion through their gills. He would also use this perfusion method to study the effects of adrenaline and vasopressin ("pitressin") on gill fluid flow and osmotic regulation in fishes. He also designed an improved Kjeldahl apparatus, which improved upon Krogh's earlier design, and allowed for more rapid determination of nitrogen content in biological samples.

They adjust their regressions on individual characteristics, industry mix and cost- of-living. They introduced regional dummies for 15 regions:Greater London, South East, West Midlands, North West, Scotland (West Coast, East Coast, North and South), Wales (South East and not South East), South West, East Midlands, East Anglia, York/Humberside, North East. The cost-of-living proxy is taken from Reward Regional Surveys Ltd which publish reports on cost-of-living and regional comparisons from 1974 up to at least 1996 The description of the construction of those cost-of-living is not clear.The descriptions in Shad and Walker (1983) and in Johnston et al.

Tempsky, Vienna, , Note: volume 3 was published in two parts Suess set out his belief that across geologic time, the rise and fall of sea levels were mappable across the earth, that is, that the periods of ocean transgression and regression were correlatable from one continent to another. Suess postulated that as sediments filled the ocean basins the sea levels gradually rose, and periodically there were events of rapid ocean bottom subsidence that increased the ocean's capacity and caused the regressions.

The Wolverine and Gulkana in Alaska, Hintereisferner, Kesselwandferner and Vernagtferner in Austria. It has also been applied to the Langtang Glacier in Nepal. Results for these tests are shown on the GMB (glacier mass balance) website at ptaagmb.com. Linear regressions of model versus manual balance measurements are based on a split-sample approach so that the calculated mass balances are independent of the temperature and precipitation used to calculate the mass balance. Regression of model versus measured annual balances yield R2 values of 0.50 to 0.60. Application of the model to Bering Glacier in Alaska demonstrated a close agreement with ice volume loss for the 1972–2003 period measured with the geodetic method.

Nicole Fortin co-authored with Sergio Firpo and Thomas Lemieux to explain an extension of the Oaxaca-Blinder decomposition method that can be applied to various distributional measures. First of all, it requires the division of distributional changes into a wage structure effect and a composition effect using a reweighting method. Second of all, it requires the further division of the two components into the contribution of each explanatory variable using recentered influence function (RIF) regressions. They demonstrate the practical aspects of the procedure by exploring how factors, such as de- unionization, education, occupations, and industry changes, impacted the polarization of U.S. male wages from the late 1980s to the mid 2010s.

In statistics, Scheffé's method, named after the American statistician Henry Scheffé, is a method for adjusting significance levels in a linear regression analysis to account for multiple comparisons. It is particularly useful in analysis of variance (a special case of regression analysis), and in constructing simultaneous confidence bands for regressions involving basis functions. Scheffé's method is a single-step multiple comparison procedure which applies to the set of estimates of all possible contrasts among the factor level means, not just the pairwise differences considered by the Tukey–Kramer method. It works on similar principles as the Working–Hotelling procedure for estimating mean responses in regression, which applies to the set of all possible factor levels.

Using so-called multifractal formalism, it can be shown that, under some well- suited assumptions, there exists a correspondence between the singularity spectrum D(h) and the multi-scaling exponents \zeta(q) through a Legendre transform. While the determination of D(h) calls for some exhaustive local analysis of the data, which would result in difficult and numerically unstable calculations, the estimation of the \zeta(q) relies on the use of statistical averages and linear regressions in log-log diagrams. Once the \zeta(q) are known, one can deduce an estimate of D(h), thanks to a simple Legendre transform. Multifractal systems are often modeled by stochastic processes such as multiplicative cascades.

In 1886, Yves Delage wondered about the simplicity of the acoela body plan organization: is it the consequence of a loss, of regressions of characters during the evolution or the acoels preserved, for certain characters, an ancestral body plan organization? These flatworms were first assimilated to Turbellaria within the phylum plathelminthes, mainly on the basis of morphological resemblances. After numerous phylogenetics and phylogenomics studies, these acoela worms were placed within the subphylum Acoelomorpha phylum Xenacoelomorpha. The phylogenetic position of the acoela is unstable and has been the subject of much discussion: arguments place them at the base of the bilaterians, before the deuterostomians/protostomians dichotomy, while others place them rather at the base of deuterostomians.

The least squares simultaneous solution of these multiple regressions used covariance between the proxy records. The results were then used to reconstruct large-scale patterns over time in the spatial field of interest (defined as the empirical orthogonal functions, or EOFs) using both local relationships of the proxies to climate and distant climate teleconnections. Temperature records for almost 50 years prior to 1902 were analysed using PCA for the important step of validation calculations, which showed that the reconstructions were statistically meaningful, or skillful. A balance was required over the whole globe, but most of the proxy data came from tree rings in the Northern mid latitudes, largely in dense proxy networks.

Concretely, in a linear regression where the errors are identically distributed, the variability of residuals of inputs in the middle of the domain will be higher than the variability of residuals at the ends of the domain: linear regressions fit endpoints better than the middle. This is also reflected in the influence functions of various data points on the regression coefficients: endpoints have more influence. Thus to compare residuals at different inputs, one needs to adjust the residuals by the expected variability of residuals, which is called studentizing. This is particularly important in the case of detecting outliers, where the case in question is somehow different than the other's in a dataset.

If the t-statistic is larger than a predetermined value, the null hypothesis is rejected and the variable is found to have explanatory power, with its coefficient significantly different from zero. Otherwise, the null hypothesis of a zero value of the true coefficient is accepted. In addition, the Chow test is used to test whether two subsamples both have the same underlying true coefficient values. The sum of squared residuals of regressions on each of the subsets and on the combined data set are compared by computing an F-statistic; if this exceeds a critical value, the null hypothesis of no difference between the two subsets is rejected; otherwise, it is accepted.

Marketing mix modeling (MMM) is statistical analysis such as multivariate regressions on sales and marketing time series data to estimate the impact of various marketing tactics (marketing mix) on sales and then forecast the impact of future sets of tactics. It is often used to optimize advertising mix and promotional tactics with respect to sales revenue or profit. The techniques were developed by econometricians and were first applied to consumer packaged goods, since manufacturers of those goods had access to accurate data on sales and marketing support. Improved availability of data, massively greater computing power, and the pressure to measure and optimize marketing spend has driven the explosion in popularity as a marketing tool.

Shortly after the game's release and the discovery of these regressions, Gearbox CEO Randy Pitchford acknowledged the issues and stated that the studio would look into them. It was reported that, as is common practice, the demo was optimized for high-end PC hardware, and that after the game was returned from its subcontractor TimeGate Studios to Gearbox, the studio made changes to optimize the game's performance for consoles. In April 2013, a class action lawsuit was filed against Gearbox Software and the game's publisher, Sega. The suit argued that these differences, along with a press embargo on publishing reviews of the final product until its release date, deceived those who pre-ordered the game based on the pre-release promotional materials, amounting to false advertising.

Chi-squared analysis and density analysis both defined functionally consistent and selective regions, or regions which showed a relatively more consistent increase in activity for the experience or perception of one emotion category across studies in the literature. Thus, a selective region could present increased activations relatively more so to one emotion category while also having a response to multiple other emotional categories. A series of logistic regressions were then performed to identify if any of the regions that were identified as consistent and selective to an emotion category were additionally specific to a given category. Regions were defined as specific to a given emotion if they showed increased activations for only one emotional category, and never showed increased activity during instances of the other emotional categories.

The test statistic used is the ratio of the mean square residual errors for the regressions on the two subsets. This test statistic corresponds to an F-test of equality of variances, and a one- or two-sided test may be appropriate depending on whether or not the direction of the supposed relation of the error variance to the explanatory variable is known. Increasing the number of observations dropped in the "middle" of the ordering will increase the power of the test but reduce the degrees of freedom for the test statistic. As a result of this tradeoff it is common to see the Goldfeld–Quandt test performed by dropping the middle third of observations with smaller proportions of dropped observations as sample size increases.

It has long been assumed that spontaneous regressions, let alone cures, from cancer are rare phenomena, and that some forms of cancer are more prone to unexpected courses (melanoma, neuroblastoma, lymphoma) than others (carcinoma). Frequency was estimated to be about 1 in 100,000 cancers; however, this proportion might be an under- or an overestimate. For one, not all cases of spontaneous regression can be apprehended, either because the case was not well documented or the physician was not willing to publish, or simply because the patient ceased to attend a clinic any more. On the other hand, for the past 100 years almost all cancer patients have received some form of treatment, and the influence of that treatment cannot always be excluded.

|
It is also reflected in the influence functions of various data points on the regression coefficients: endpoints have more influence. This can also be seen because the residuals at endpoints depend greatly on the slope of a fitted line, while the residuals at the middle are relatively insensitive to the slope. The fact that the variances of the residuals differ, even though the variances of the true errors are all equal to each other, is the principal reason for the need for studentization. It is not simply a matter of the population parameters (mean and standard deviation) being unknown – it is that regressions yield different residual distributions at different data points, unlike point estimators of univariate distributions, which share a common distribution for residuals.

Protective factors are conditions or attributes (skills, strengths, resources, supports or coping strategies) in individuals, families, communities or the larger society that help people deal more effectively with stressful events and mitigate or eliminate risk in families and communities.A web page for the prevention of suicide In the field of Preventive Medicine and Health Psychology, Protective Factors refer to any factor that decreases the chances of a negative health outcome occurring. Conversely, a Risk factor will increase the chances of a negative health outcome occurring. Just as statistical correlations and regressions can examine how a range of independent variables impact a dependent variable, we can examine how many Protective and Risk factors contribute to the likelihood of an illness occurring.

Reception to the Nintendo 2DS was mixed; while Nintendo was praised for how it priced and positioned the 2DS alongside its higher-end counterparts, much of its criticism was directed towards its regressions in comparison to the 3DS, such as a design that some considered less appealing than that of the 3DS, its lower sound quality, and its battery life. However, the 2DS's design was praised by some critics for being more robust and comfortable to hold than the 3DS, especially for its target market. Some critics also felt that the lack of 3D support was an admission by Nintendo that the concept was a gimmick; however, Nintendo has since stated that autostereoscopic 3D would remain a part of their future plans.

Aliens: Colonial Marines, a first-person shooter developed by Gearbox Software and set in the universe of the Alien franchise, was criticized at launch for containing bugs, poorly-implemented A.I., unbalanced gameplay, low-quality graphics, and a poorly-implemented co-op mode. A couple of said issues have since been adjusted or fixed to a certain degree. The game's story also drew criticism for its lack of a consistent continuity with the Alien films, despite claims from the developers that the events of the game were supposed to be canon to the film series. Particular criticism was directed towards discrepancies in the game's quality between pre-release builds demonstrated at events and in promotional materials—the former purporting to feature "actual gameplay", and the final product, including lower graphics quality, missing levels, and other regressions.

Marcus Rediker, 2004, Villains of All Nations, p. 8. Martin Mares, drawing on both Cordingly and Rediker, took their arguments about the periodization of the Golden Age of Piracy even further in his seminal work The British Contribution to the Development of Piracy in the Golden Age of Piracy, proposing that the longer periodization can be also understood as an uninterrupted and continuous process with its points of peaks and regressions. Besides, Mares argued that such interpretation allows us to fully understand how the golden age of piracy helped the British to develop the understanding of their imperial policy as one single domain with interconnected interests rather than separate Western and Eastern spheres of influence. This argument was later reinforced from the economical perspective by Nicolás Rodríguez Arosemena.

Otto Fenichel summarized early psychoanalytic studies of coping mechanisms in children as "a gradual substitution of actions for mere discharge reactions...[&] the development of the function of judgement" – noting however that "behind all active types of mastery of external and internal tasks, a readiness remains to fall back on passive-receptive types of mastery." In adult cases of "acute and more or less 'traumatic' upsetting events in the life of normal persons", Fenichel stressed that in coping, "in carrying out a 'work of learning' or 'work of adjustment', [s]he must acknowledge the new and less comfortable reality and fight tendencies towards regression, towards the misinterpretation of reality", though such rational strategies "may be mixed with relative allowances for rest and for small regressions and compensatory wish fulfillment, which are recuperative in effect".

Windows 10 also introduced the Microsoft Edge web browser, a virtual desktop system, a window and desktop management feature called Task View, support for fingerprint and face recognition login, new security features for enterprise environments, and . Windows 10 received mostly positive reviews upon its original release. Critics praised Microsoft's decision to provide a desktop-oriented interface in line with previous versions of Windows, contrasting the tablet-oriented approach of Windows 8, although Windows 10's touch-oriented user interface mode was criticized for containing regressions upon the touch-oriented interface of its predecessor. Critics also praised the improvements to Windows 10's bundled software over Windows 8.1, Xbox Live integration, as well as the functionality and capabilities of the Cortana personal assistant and the replacement of Internet Explorer with Edge.

Maddala's first faculty position was at Stanford University. He held the University Eminent Scholar position at Ohio State University upon his death; previous university affiliations included Stanford University (1963–1967), University of Rochester (1967–1975), and the University of Florida (1975–1993). Maddala published over 110 scholarly papers and wrote 12 books covering most of the emerging areas of econometrics. His 1983 book titled Limited Dependent and Qualitative Variables in Econometrics is now regarded as a classic and seminal text for advanced studies in econometrics. In econometrics methodology, Maddala’s key areas of research and exposition included distributed lags, generalized least squares, panel data, simultaneous equations, errors in variables, income distribution, switching regressions, disequilibrium models, qualitative and limited dependent variable models, self-selection models, outliers and bootstrap methods, unit roots and cointegration methods, and Bayesian econometrics.

The idea that the "Akashic records" held past life data set the stage, whereby Western practitioners of the paranormal could sidestep the notion of forgetfulness that, in traditional teachings about reincarnation, had prevented memories of former lives from being accessed. An early report for a human accessing past life information during a trace state comes from 1923, when Edgar Cayce, while answering questions posed by Arthur Lammers (publisher) in a trace state, spoke of Lammers' past lives and of reincarnation. The use of hypnosis for past life regressions is said to have been developed by A. R. (Asa Roy) Martin of Sharon, Pennsylvania, who published Researches in Reincarnation and Beyond in 1942.; the author of this 32-page booklet is a member of the Association for Past Life Research and Therapies (APRT).

Since human cells originated from a single-celled organism, several scientists have postulated that the pathogenic behavior of cancer cells is likely due to the re-expression of past traits and behaviors (atavism) derived from their past evolutionary experience as independent, single-celled organisms. This reversion or de-evolution of a differentiated cell to its ancestral undifferentiated, unicellular form has suggested that cancer is a cellular atavism. The objective of atavistic chemotherapy clinical trial is to determine whether there is a benefit for patients with inoperable or metastatic cancers when treated successfully with combinations of selected drugs conventionally used in medical practice to kill single-celled organisms, such as antibacterial, anti-fungal and anti-protozoal drugs. Preliminary results show that atavistic chemotherapy can induce complete cancer regressions of several types of metastatic and inoperable cancers.

However, in his later monograph of 1980, Keys included multivariate regressions in which sugar is added to the regression and saturated fat is controlled for. In this regression, Keys found that sugar was not statistically significantly related to incidence of heart disease when dietary saturated fat was controlled for. Today, sugar intake is known to increase the risk of diabetes mellitus, and increased dietary intake of sugar is known to be associated with higher blood pressure, unfavorable blood lipids and cardiometabolic risks. However, a 2010 conference debate of the American Dietetic Association expressed concern over the health risks of replacing saturated fats in the diet with refined carbohydrates, which carry a high risk of obesity and heart disease, particularly at the expense of polyunsaturated fats which may have health benefits.

Mares' specialization is the early modern period with an expertise in the history of maritime piracy. In 2015, Mares first introduced his theory of 'mutual contribution' in The British Contribution to the Development of Piracy in the Golden Age of Piracy, supporting his secondary argument that the longer periodization of this era should be understood as an uninterrupted and continuous process with its points of peaks and regressions. From the economical perspective, these ideas were later expanded by Nicolás Rodríguez Arosemena. Later, Mares expanded some of his ideas in The Role of Jamaica in Fostering Maritime Piracy In the Atlantic Ocean, 1655-1702, presenting pirates as an integral element of British imperial endeavour by an implementation of a complex framework of relations between influential members involved in Jamaican colonial administration and prominent individuals of pirate crews.

On August 6, 2014, Twitch introduced an updated archive system, with multi-platform access to highlights from past broadcasts by a channel, higher quality video, increased server backups, and a new Video Manager interface for managing past broadcasts and compiling "highlights" from broadcasts that can also be exported to YouTube. Due to technological limitations and resource requirements, the new system contained several regressions; the option to archive complete broadcasts on an indefinite basis ("save forever") was removed, meaning that they can only be retained for a maximum of 14 days, or 60 for partners and Turbo subscribers. While compiled highlights can be archived indefinitely, they were limited to two hours in length. In addition, Twitch introduced a copyright fingerprinting system that would mute audio in archived clips if it detected a copyrighted song in the stream.

In econometrics, the seemingly unrelated regressions (SUR) or seemingly unrelated regression equations (SURE) model, proposed by Arnold Zellner in (1962), is a generalization of a linear regression model that consists of several regression equations, each having its own dependent variable and potentially different sets of exogenous explanatory variables. Each equation is a valid linear regression on its own and can be estimated separately, which is why the system is called seemingly unrelated, although some authors suggest that the term seemingly related would be more appropriate, since the error terms are assumed to be correlated across the equations. The model can be estimated equation-by-equation using standard ordinary least squares (OLS). Such estimates are consistent, however generally not as efficient as the SUR method, which amounts to feasible generalized least squares with a specific form of the variance-covariance matrix.

Tobacco policies that limit the sale of cigarettes to minors and restrict smoking in public places are important strategies to deter youth from accessing and consuming cigarettes.Maria T. Botello-Harbaum, Denise L. Haynie, Ronald J. Iannotti, Jing Wang, Lauren Gase, Bruce Simons-Morton; Tobacco control policy and adolescent cigarette smoking status in the United States, Nicotine & Tobacco Research, Volume 11, Issue 7, 1 July 2009, Pages 875–885, Amongst youth in the United States, for example, when compared with students living in states with strict regulations, young adolescents living in states with no or minimal restrictions, particularly high school students, were more likely to be daily smokers. These effects were reduced when logistic regressions were adjusted for sociodemographic characteristics and cigarette price, suggesting that higher cigarette prices may discourage youth to access and consume cigarettes independent of other tobacco control measures.

Wallace's father, Henry Cantwell Wallace, served as secretary of agriculture from 1921 to his death in 1924. Wallace became a full-time writer and editor for the family-owned paper, Wallace's Farmer, after he graduated college in 1910. He was deeply interested in using mathematics and economics in agriculture, and he learned calculus as part of an effort to understand hog prices.Culver & Hyde (2000), pp. 37–39 He also wrote an influential article with pioneering statistician George W. Snedecor on computational methods for correlations and regressions After the death of his grandfather in 1916, Wallace became the co-editor of Wallace's Farmer alongside his father.Culver & Hyde (2000), p. 42–44 In 1921, Wallace assumed leadership of the family paper after his father accepted appointment as secretary of agriculture under President Warren G. Harding.Culver & Hyde (2000), pp.

Gates later said that Windows 7 would also focus on performance improvements. Steven Sinofsky later expanded on this point, explaining in the Engineering Windows 7 blog that the company was using a variety of new tracing tools to measure the performance of many areas of the operating system on an ongoing basis, to help locate inefficient code paths and to help prevent performance regressions. Senior Vice President Bill Veghte stated that Windows Vista users migrating to Windows 7 would not find the kind of device compatibility issues they encountered migrating from Windows XP. An estimated 1,000 developers worked on Windows 7. These were broadly divided into "core operating system" and "Windows client experience", in turn organized into 25 teams of around 40 developers on average. In October 2008, it was announced that Windows 7 would also be the official name of the operating system.

When time series X Granger-causes time series Y, the patterns in X are approximately repeated in Y after some time lag (two examples are indicated with arrows). Thus, past values of X can be used for the prediction of future values of Y. The Granger causality test is a statistical hypothesis test for determining whether one time series is useful in forecasting another, first proposed in 1969. Ordinarily, regressions reflect "mere" correlations, but Clive Granger argued that causality in economics could be tested for by measuring the ability to predict the future values of a time series using prior values of another time series. Since the question of "true causality" is deeply philosophical, and because of the post hoc ergo propter hoc fallacy of assuming that one thing preceding another can be used as a proof of causation, econometricians assert that the Granger test finds only "predictive causality".

FUA is more fine-grained as it allows a single write operation to be forced to stable media and thus has smaller overall performance impact when compared to commands that flush the entire disk cache, such as the ATA FLUSH CACHE family of commands. Windows (Vista and up) supports FUA as part of Transactional NTFS, but only for SCSI or Fibre Channel disks where support for FUA is common. It is not known whether a SATA drive that supports FUA write commands will actually honor the command and write data to disk platters as instructed; thus, Windows 8 and Windows Server 2012 instead send commands to flush the disk write cache after certain write operations. Although the Linux kernel gained support for NCQ around 2007, SATA FUA remains disabled by default because of regressions that were found in 2012 when the kernel's support for FUA was tested.

Another seminal contribution to nonlinear learning models was to enable a nonparametric basis function pursuit via sparse kernel-based learning, what led to the first approach to tensor completion and extrapolation with applications to spectrum cartography, network flow prediction, and imputation of gene expression data. A cornerstone of data science is learning from big data, where the latter refers to the volume (dimensionality and number) of data, their velocity (of streaming data), and variety (multimodality). To extract the sought information that often resides in small subspaces, and cope with subsampled or missing data, Giannakis and collaborators put forth an online censoring approach for large- scale regressions and trackers, where only informative data are retained for learning. Instead of censoring, they also adopted a limited number of random data projections (sketches) and validated whether they contain informative data, before employing them for (subspace) clustering to obtain desirable performance-complexity tradeoffs.

The Galaxy S6 received a generally positive reaction from early reviewers, noting its higher quality design over previous Samsung devices, along with refinements to its camera, the high quality of its display, and the significantly smaller amount of "bloat" in the device's software. Anandtech believed that the S6's new fingerprint reader was comparable in quality to Apple's Touch ID system. The Verge concluded that the S6 and S6 Edge were "the first time I’ve felt like Samsung might finally be grappling with the idea of what a smartphone ought to be on an ontological level." Some critics raised concerns over the S6's regressions in functionality over the Galaxy S5, particularly the battery being both smaller in capacity and non-user-replaceable, the missing microSD card slot, and lack of water resistance, arguing that it could alienate power users who were attracted to the Galaxy S series due to their inclusion.

The analysis published by Christine Argot in 2002 about the evolution of predatory borhyaenoids suggests that Thylacosmilus was a specialized form, which have a limited stereoscopic vision with small eyes, with an overlap of 50-60°, very low compared with modern predators, but the ossified and great auditory bulla and the muscular body would indicate that it could be an ambush predator in open and relatively dry environments, where the sound absorption is lesser than in more humid areas, and the acute hearing could compensate the limited vision. Argot suggested that Thylacosmilus maybe was an nocturnal hunter, as modern lions. A 2005 study published by Wroe et al. analysing bite-forces with the use of regressions on body mass and applying the model of "dry skull" in which the jaw is modeled as a lever based in relations between the skull dimensions and the jaw muscles, was employed in some extinct and extant placental and metatherian predatory mammals.

Unit tests, functional tests and performance tests are developed using built-in quality assurance frameworks in order to make sure that the implementation matches specified document oriented use cases and in order to prevent regressions.. This approach departs from data structure oriented modeling and from the idea that ERP implementation should at the same time change the processes of an organization and its information system. Rather than forcing organizations to adopt preset business processes, or so-called best practices provided by the ERP vendor, the ERP5 implementation process tries to capture efficient practices which are already implemented in the organization and map them to the UBM model. The risk of failure and the implementation costs of ERP implementation in large organizations are thus reduced through this approach. The ERP5 implementation process was successfully applied to the computerization of business processes of a Central Bank.. However, this implementation approach does not fit with the budget constraints of small companies or with the time constraints of newly created organizations.

For his postdoctoral research Mann joined Bradley and tree ring specialist Malcolm K. Hughes to develop a new statistical approach to reconstruct underlying spatial patterns of temperature variation combining diverse datasets of proxy information covering different periods across the globe, including a rich resource of tree ring networks for some areas and sparser proxies such as lake sediments, ice cores and corals, as well as some historical records. Their global reconstruction was a major breakthrough in evaluation of past climate dynamics, and the first eigenvector-based climate field reconstruction (CFR) incorporating multiple climate proxy data sets of different types and lengths into a high-resolution global reconstruction. To relate this data to measured temperatures, they used principal component analysis (PCA) to find the leading patterns, or principal components, of instrumental temperature records during the calibration period from 1902 to 1980. Their method was based on separate multiple regressions between each proxy record (or summary) and all of the leading principal components of the instrumental record.

Android 9.0 "Pie" was released for the G7 One in November 2018, followed by Android 10 in December 2019. MobileSyrup noted some regressions over the G7 ThinQ due to the differences in hardware, especially in regards to battery life (such as the SoC downgrade resulting in a lack of Quick Charge 4+ support, and the G7 line's use of LCD over OLED as affecting its efficiency), but that the G7 One was "mostly fluid" and retained much of the ThinQ's hardware features (such as its audio support) whilst excluding LG's often-criticized user experience. Due to its positioning and launch pricing, comparisons were drawn to the OnePlus 6T, but it was argued that although the 6T had a Snapdragon 845, a larger battery and an OLED display, the G7 One did have a sharper display with HDR support, a headphone jack with a DAC, and official IP certification for waterproofing. In December 2018, the G7 One was released in Japan as the LG X5 Android One.

A review of the clinical research concluded that hydrazine sulfate has never been shown to act as an anticancer agent; patients do not experience remissions or regressions of their cancer, and patients do not live longer than non-treated patients.. Some academic reviews of alternative cancer treatments have described the compound as a "disproved and ineffective treatment for cancer".Hydrazine sulfate / Hydrazine sulphate from the British Columbia Cancer Agency Joseph Gold's claims have been questioned by the American Cancer Society, and other investigators have been unable to repeat or confirm these results. Gold is reported not to trust the motives or results of other investigators, with CNN quoting him as stating that "they've been out to get hydrazine sulfate, and I don't know why".Elizabeth Cohen Regulators warn about online cancer 'cures' CNN December 5, 2000 In response to these results, an uncontrolled clinical trial was carried out at the Petrov Research Institute of Oncology in St. Petersburg over a period of 17 years,.

These proposals were controversial, and criticized especially as regressions towards a capitalist economic system. Critics also argued that reliance on profitability would skew the proportions in which different goods were produced.Katz, Economic Reform (1972), p. 67. "Thus, despite Liberman's assurances that price formation would be in the hands of the state and although he appeared to suggest a manipulative approach to price policy, the conservative critics were quick to point out that Liberman's proposals 'lead to the conclusion that the methodological basis of price formation in a planned socialist economy should be the prices of production, which is characteristic of the capitalist system of economy.'"Tubis, Decision-Making in the Soviet Economic Bureaucracy (1973), pp. 87–88. V. Trapeznikov advocated a position similar to Liberman's, in Pravda, August 1964, writing that > the time has come to discard the obsolete forms of economic management based > on directive norms, and to pass over to a simpler, cheaper and more > efficient type of control of the activities of enterprises.

Size (orange) compared to that of a human and other predators Body mass for sparassodonts is difficult to estimate, since these animals have relatively large heads in proportion to their bodies, leading to overestimations, particularly when compared with skulls of modern members of Carnivora, which have different locomotory and functional adaptations, or with those of the recent predatory marsupials, which do not exceed 30 kg of body mass. Recent methods, like Ercoli and Prevosti's (2011) linear regressions on postcranial elements that directly support the body's weight (such as tibiae, humeri and ulnae), comparing Thylacosmilus to both extinct and modern carnivorans and metatherians, suggest that it weighed between , with one estimate suggesting up to , about the same size as a modern jaguar. The differences in weight estimations may be due to the individual size variation of the specimens studied in each analysis, as well as the different samples and methods used. In any case, the weight estimations are consistent for terrestrial species that are generalists or have some degree of cursoriality.

Nonetheless, it was found that the take-the-best heuristic can yield more accurate choices than other models of decision-making including multiple linear regression which considers all available information. Such results have been replicated empirically in comparisons with sophisticated statistics and machine-learning models, such as CART decision trees, random forests, Naive Bayes, regularized regressions, support vector machines, and so on, and across a large number of decision problems (including choice, inference, and forecasting) and real-world datasets—for reviews see. As said above, to explain such success of take-the-best, one needs to figure out which environmental characteristics promote it and which do not. According to the theory of ecological rationality, examples of environmental characteristics that lead to the relatively higher accuracy of take-the-best compared to other models, include the (i) scarce or low quality of available information, (ii) high dispersion of validities of the attributes (also called the non- compensatoriness condition), and (iii) the presence of options dominating other options, including the conditions of simple and cumulative dominance.

IGN considered the New 2DS XL to be an improvement over the "ugly doorstop-like" 2DS, praising its incorporation of features from the New 3DS XL into a device with a thinner and more "comfortable" form factor. Other changes were noted, such as using flaps to protect the game and SD card slots (the latter also removing the need to use tools to access it), and better-feeling shoulder buttons than the New 3DS XL. Regressions were also noted, however, such as its screens having a "washed out" appearance and lacking contrast, the top screen having a mirror-like coat that diminished viewing angles, the speakers sounding "muffled", and the short length of the included stylus. The New 2DS XL was recommended for users who did not need 3D but still wanted to play the platform's exclusives. TechRadar was similarly positive, but also noting that the hinge now protruded from the back of the device (thus making it look less streamlined when closed), its battery life was "underwhelming", and the timing of its launch was at odds with the release of Nintendo Switch.
