Regression dilution — is a statistical phenomenon also known as attenuation . Consider fitting a straight line for the relationship of an outcome variable y to a predictor variable x, and estimating the gradient (slope) of the line. Statistical variability,… … Wikipedia
Regression testing — is any type of software testing which seeks to uncover software regressions. Such regressions occur whenever software functionality that was previously working correctly stops working as intended. Typically regressions occur as an unintended… … Wikipedia
Regression toward the mean — In statistics, regression toward the mean (also known as regression to the mean) is the phenomenon that if a variable is extreme on its first measurement, it will tend to be closer to the average on a second measurement, and a fact that may… … Wikipedia
Robust regression — In robust statistics, robust regression is a form of regression analysis designed to circumvent some limitations of traditional parametric and non parametric methods. Regression analysis seeks to find the effect of one or more independent… … Wikipedia
Bayesian linear regression — In statistics, Bayesian linear regression is a Bayesian alternative to the more well known ordinary least squares linear regression.Consider standard linear regression problem, where we specify the conditional density of y, given x, predictor… … Wikipedia
Past life regression — (PLR) is a therapeutic technique that uses light levels of hypnosis to activate memories, or pseudo memories, that appear to represent past lives. PLR is typically undertaken either in pursuit of a spiritual experience, or in a therapeutic… … Wikipedia
Partial regression plot — In applied statistics, a partial regression plot attempts to show the effect of adding an additional variable to the model (given that one or more indpendent variables are already in the model). Partial regression plots are also referred to as… … Wikipedia
Deming regression — Deming regression. The red lines show the error in both x and y. This is different from the traditional least squares method which measures error parallel to the y axis. The case shown, with deviations measured perpendicularly, arises when x and… … Wikipedia
Hedonic regression — In economics, hedonic regression, also hedonic demand theory, is a method of estimating demand or value. It decomposes the item being researched into its constituent characteristics, and obtains estimates of the contributory value of each… … Wikipedia
Least-squares estimation of linear regression coefficients — In parametric statistics, the least squares estimator is often used to estimate the coefficients of a linear regression. The least squares estimator optimizes a certain criterion (namely it minimizes the sum of the square of the residuals). In… … Wikipedia
No true Scotsman — For the practice of wearing a kilt without undergarments, see True Scotsman. No true Scotsman is an informal logical fallacy, an ad hoc attempt to retain an unreasoned assertion.[1] When faced with a counterexample to a universal claim, rather… … Wikipedia
