Hi All,

Can anyone clearly explain the difference between the three procedures :GLM/GLIMMIX/GENMOD.

Thanks!

Both proc glm and proc genmod do the General Linear Model.But proc glm use OLS to fit model ,while proc genmod use MLE to fit.

proc glimmix usually is for Mixed General Linear Model, not like GLM/GENMOD which only consider effect as FIXED .
