Hi, I am using PROC MIXED with the code below, but the results are not displaying any p-values in both the Solution for Fixed Effects table and the Type 3 Tests of Fixed Effects table. In place of a p-value, there is a "." Is there something missing from the code that is preventing and/or interferring with SAS computing the p-values? PROC MIXED DATA= GGGImp.TNFa METHOD= REML; CLASS sequence (ref= "AB") treatment (ref="A") time (ref="V1") period (ref= "P1"); MODEL TNFalpha = sequence treatment time period / SOLUTION; RANDOM intercept / SUBJECT=subjID g vcorr; RUN; Thanks!
