Here I write about SAS, Rasch Model, HLM (Multilevel modeling), etc.
NEWS! PROC GLIMMIX is the solution. SAS now has the production version.
I wrote a lot about SAS PROC MIXED on this website, but I use PROC GLIMMIX almost exclusively.
PROC MIXED and GLIMMIX use almost the same syntax, so no worry. GLIMMIX does everything MIXED does. GLIMMIX accomodates logistic regressions and other things, so I recommed GLIMMIX.
