Hello, using the PROC GLIMMIX - LSMEANS I would like to get the differences between the groups (A, B, C and D) for each time (1, 2, 3 and 4). Exemple: Only for Time = 1 Tukey-Kramer Grouping for Grupo Least Squares Means (Alpha=0.05) LS-means with the same letter are not significantly different. Grupo Estimate Grupo D 1.8 A Grupo B 1.7 B B Grupo A 1.7 B B Grupo C 1.6 B Only for time 2: Tukey-Kramer Grouping for Grupo Least Squares Means (Alpha=0.05) LS-means with the same letter are not significantly different. Grupo Estimate Grupo B 1.9 A Grupo C 1.5 B B Grupo D 1.3 B B Grupo A 1.0 B Only for time 3 ... The same idea... Only for time 4 ... The same idea... My line commands were showed below: PROC GLIMMIX DATA=WORK.Example;
CLASS ID Group Time;
MODEL var_study = Group Time Group*Time / DDFM=KR DIST=GAUSSIAN;
RANDOM Time / RESIDUAL TYPE=CS SUBJECT = ID;
LSMEANS Time*Group / LINES ADJUST=TUKEY;
RUN;
QUIT; /* Dosen´t work the sintaxe = Lsmeans Group*Time / Slice=Time adjust=tukey; So, in order to get the differences between the groups (A, B, C and D) for each time (1, 2, 3 and 4), how do I construct the LSMEANS procedure? Thanks a lot, Mingoti, Rodolfo.
