@alexal Many thanks for your promptly reply!   The program runs smoothly with your option (it works with 1e-11 too).   When I run the program in SAS 9.3 & 9.4 with the same singluar=1e-8 I do expect the Least Squares Means being identical for both versions. This is not the case. I get the same Estimate, DF & Pr > |t|, but Standard Error & T values are different. Which is the reason?   Many thanks for helping me! ... View more

Good morning   I need your help to understand the difference of running Proc MIXED in SAS 9.3 & SAS 9.4. The same program (same dataset) running smoothly on SAS 9.3 when I run it on SAS 9.4 returns the 'WARNING: Stopped because of infinite likelihood.'. In the data there are no repeated values. ods output lsmeans=STAT00; proc mixed data = rawda MAXFUNC=5000; by paramcd param; class usubjid studyid avisitn basecn ; model chg = studyid avisitn basecn avisitn*basecn /solution; repeated avisitn / subject = usubjid(studyid) ; lsmeans basecn*avisitn ; PARMS / NOITER ; run; ods output close;   Please help me to understand what did change. Many thanks in advance ... View more
