TESTING FOR NORMALITY IN THE LINEAR REGRESSION MODEL: AN EMPIRICAL LIKELIHOOD RATIO TESTLauren BinDavid GilesDavid Giles
In linear regression the unknown true errors are often estimated by the ordinary least squares residuals. These estimates suffer from shrinkage and superimposed normality effects and may give a misleading impression of the true error distribution. A new method, RMOLS, is proposed to improve the esti...
These comprise a very large part of the statistical models used in ecology and include t tests, simple and multiple linear regression, polynomial regression, and analysis of variance (ANOVA) and covariance (ANCOVA). There is a widely held belief that the normality assumption pertains to the raw...

It is proved that if the conditional distribution of one linear form in two independent (not necessarily identically distributed) random variables given another is normal, then the variables are normal. The result complements a series of characterizations of normal distribution via different properties ...
Linear Least Squares is a very well known technique for parameter estimation, which is used even when sub-optimal, because of its very low computational re... M Krikheli,A Leshem 被引量: 1发表: 2017年 A Test of U-type for Goodness-of-fit in Regression Models Through Martingale Difference...
> > For instance, in linear regression they generate residuals and check it by -qnorm- or -pnorm- (qnorm e). Also, to check heteroscedasticity they make a graph of the residuals of the model against the predicted values. > > So, if the residuals will not be normal because of ...

Regression tests of linearity are used to examine the adequacy of linear scoring systems for explanatory variables, initially recorded on an ordinal scale. Examples from recent psychological and medical research are given in which the methods have led to some insight into subject-matter....
