Hi,

I'm using SAS proc mixed to run mixed linear model with the outcome variable measured at 4 time points (baseline, 1 month, 3 months, 6 months). I'm using the OUTPRED command to get a data set with individual predicted values on the outcome variable. I am getting the data set, but it only gives predicted values for the first 3 time points (baseline, 1 month, and 3 months). I'm wondering if someone could tell me how to get the individual predicted values for that last time point (6 months). Thanks for your help!

Here's the code I'm using to run the analysis and generate the data set:

proc mixed data=transpose method=ml noclprint covtest cl; class sid; model pctabs = time time2 tx2 tx2*time tx2*time2 /solution cl ddfm=bw notest outpred=pred1; random time / type=un subject=sid; run;
