Problem Note 17511: Incorrect output when REPEATED statement uses TYPE=ANTE(1) and data not
sorted by repeated effect within each subject
If a MIXED model contains a REPEATED statement with TYPE=ANTE(1) and the
data are not sorted by the repeated effect within each subject, then all
of the results from PROC MIXED will be incorrect. For example, if the
REPEATED statement is
repeated time / subject=id type=ante(1);
then the data must be sorted by ID TIME to get the correct results.
To circumvent this problem, sort the data in the appropriate order.
