Regression analysis controls for other relevant variables by including them as regressors ( explanatory variables ).

Regression analysis producing statistically significant negative relationships indicates that two individuals can be less genetically alike than two random ones on average ( Hamilton 1970, Nature & Grafen 1985 Oxford Surveys in Evolutionary Biology ).

There are also programs specifically written to do curve fitting ; they can be found in the lists of statistical and numerical analysis programs as well as in: Category: Regression and curve fitting software.

* Regression tree analysis is when the predicted outcome can be considered a real number ( e. g. the price of a house, or a patient ’ s length of stay in a hospital ).

The term Classification And Regression Tree ( CART ) analysis is an umbrella term used to refer to both of the above procedures, first introduced by Breiman et al.

Empirical models that attempt to estimate the public investment and economic growth link involve a wide variety including: the Cobb-Douglas production function ; a behavioral approach cost / profit function which includes public capital stock ; Vector Auto Regression ( VAR ) models ; and government investment growth regressions.

STATISTICA is customizable and may be used to call external code modules, including R. This collection of data mining and machine learning algorithms includes: Support Vector Machines, EM and k-Means Clustering, Classification & Regression Trees, Generalized Additive Models, Independent Component Analysis, Stochastic Gradient Boosted Trees, Ensembles of Neural Networks, Automatic Feature Selection, MARSplines, CHAID Trees, Nearest Neighbor Methods, Association Rules, and Random Forests.

Regression methods are important in econometrics because economists typically cannot use controlled experiments.

Regression methods continue to be an area of active research.

Hedonic Regression methods are used to estimate these price differentials.

Regression testing can be used to test a system efficiently by systematically selecting the appropriate minimum set of tests needed to adequately cover a particular change.

Regression testing can be used not only for testing the correctness of a program, but often also for tracking the quality of its output.

Regression tests can be broadly categorized as functional tests or unit tests.

Regression towards the mean can be defined for any bivariate distribution with identical marginal distributions.

Regression techniques can be used to determine if a specific case within a sample population is an outlier via the combination of two or more variable scores.

* Regression of Weakly Correlated Data — How linear regression mistakes can appear when Y-range is much smaller than X-range

* R: The function for fitting a generalized linear model in R is glm (), and can be used for Poisson Regression

Regression to the mean in sports performance may be the reason for the “ Sports Illustrated Cover Jinx ” and the “ Madden Curse ”.

Regression toward the mean simply says that, following an extreme random event, the next random event is likely to be less extreme.

* Regression test-to be performed on an existing operational product, to verify that existing functionality didn't get broken when other aspects of the environment are changed ( e. g., upgrading the platform on which an existing application runs ).

Regression is first used to fit more

* Robust statistics-Data sets used in Robust Regression and Outlier Detection ( Rousseeuw and Leroy, 1986 ).

Regression analysis is widely used for prediction and forecasting, where its use has substantial overlap with the field of machine learning.

Regression analysis is also used to understand which among the independent variables are related to the dependent variable, and to explore the forms of these relationships.

In statistics, the explained sum of squares ( ESS ), alternatively known as the Model Sum of Squares or Sum of Squares due to Regression, is a quantity used in describing how well a model, often a regression model, represents the data being modelled.
