I use glmm.admb in glmmADMB library in R and PROC GLIMMIX in SAS to
test the random effects for
the same data.

For example, I want to test the Area effect, on SAS, I used,


Code:
random intercept / subject = Area;


In glmm.admb, should I state,


Code:
glmm.admb(...,random=~1,group="Area",....)


Because they gave the different results, I think I made mistakes.


Cheers
