Hi there, I often use SAS Macro PDMIX800 for mean comparison/grouping along with SAS Proc Mixed. I used this 'Proc Glimmix' to do the same. However, I am confused for one thing. When I compared both of results, I found that Glimmix result is similar to Proc Mixed assuming equal variance. However, the addition of "repeated statement' for modeling the variance in the case of the unequal variance in Proc Mixed gives a different result. I tried to add the same repeated statement in Proc Glimmix but could not. So, I am wondering if this result of mean separation from Proc Glimmix in a case of a dataset with unequal variance is acceptable or there is any other way to model the variance to obtain same results from PDMIX800 and Proc Gliimmix.
