Yes, it is a very unifying procedure of many different analyses (hence the name).
It can handle all the models included in Generalized Linear Mixed Models. That means all statistical analyses appeared in many elementary textbooks are supported.
It is a fantastic procedure that I became to use everyday. Together with powerful LSMESTIMATE statement it is a real giant.
An update: I was looking for calculating odds ratios in a logistic regression model where an interaction term is included. Wow, GLIMMIX has an option oddsratio in a lsmeans statement (possibly in lsmestimate too) which does the job perfectly. With slicediff, ilink and cl options, that was just what I was looking for. Awesome. GLIMMIX will be my first choice of procedures from now on.
