so I suppose for repeated measures without missing values, xtmixed or
r.anova are kind of the same thing !

Amir,
Yes, -xtmixed, reml- without missing observations yields the exact
same results as repeated measures anova. There are additional
benefits to -xtmixed- even for complete data. -xymixed- allows for
covariance structure other than compound symmetry (exchangeable), such
as, ar1, using the -residuals- option. With -xtmixed- you can also
have equally spaced time intervals that vary by subject.
