Generalized Gaussian distribution — (GGD)= A random variable X has generalized Gaussian distribution if its probability density function (pdf) is given byf(x;m,sigma,alpha)=a exp( |(x m)/b|^alpha) ,x in R, where m is the mean of the distribution, sigma is the standard deviation,… … Wikipedia
Generalized linear model — In statistics, the generalized linear model (GLM) is a flexible generalization of ordinary least squares regression. It relates the random distribution of the measured variable of the experiment (the distribution function ) to the systematic (non … Wikipedia
Variance inflation factor — In statistics, the variance inflation factor (VIF) is a method of detecting the severity of multicollinearity. More precisely, the VIF is an index which measures how much the variance of a coefficient (square of the standard deviation) is… … Wikipedia

Generalized extreme value distribution — Probability distribution name =Generalized extreme value type =density pdf cdf parameters =mu in [ infty,infty] , location (real) sigma in (0,infty] , scale (real) xiin [ infty,infty] , shape (real) support =x>mu sigma/xi,;(xi > 0) x … Wikipedia
Analysis of variance — In statistics, analysis of variance (ANOVA) is a collection of statistical models, and their associated procedures, in which the observed variance in a particular variable is partitioned into components attributable to different sources of… … Wikipedia
Multivariate analysis of variance — (MANOVA) is a generalized form of univariate analysis of variance (ANOVA). It is used when there are two or more dependent variables. It helps to answer : 1. do changes in the independent variable(s) have significant effects on the dependent … Wikipedia
Allan variance — The Allan variance, named after David W. Allan, is a measurement of stability in clocks and oscillators. It is also known as the two sample variance.It is defined as one half of the time average of the squares of the differences between… … Wikipedia
Normal variance-mean mixture — In probability theory and statistics, a normal variance mean mixture with mixing probability density g is the continuous probability distribution of a random variable Y of the form where α and β are real numbers and σ > 0 and random variables… … Wikipedia
Computational formula for the variance — See also: Algorithms for calculating variance In probability theory and statistics, the computational formula for the variance Var(X) of a random variable X is the formula where E(X) is the expected value of X. A closely related identity can be… … Wikipedia
Feasible generalized least squares — (FGLS or Feasible GLS) is a regression technique. It is similar to generalized least squares except that it uses an estimated variance covariance matrix since the true matrix is not known directly.The following description follows loosely the… … Wikipedia
