The following two examples illustrate the most common formulations of the general linear mixed model. You can set up this model in PROC MIXED in two different but equivalent ways: proc mixed; class ...

Ordinary linear regression (OLR) assumes that response variables are continuous. Generalized Linear Models (GLMs) provide an extension ... Below are three data examples which will be used in the ...

Many response variables are handled poorly by regression models when the errors are assumed to be normally distributed. For example, modeling the state ... a large class of regression models called ...

Linear mixed model (LMM) methodology is a powerful ... This approach eventually leads to a special area of statistics called the generalized linear model (GLM) (McCullagh and Nelder, 1989).
