Re: st: repeated measures anova
.
On second thought, I should not have guessed at the syntax, and I hope
I didn't cause further confusion! You should check out Linear Mixed
Models: A Practical Guide Using Statistical Software, Chapter 5, from
the Stata bookstore which provides correct syntax in SAS, SPSS, R, and
Stata for the analysis of a two factor within subjects repeated
measures example. I would not use ANOVA for the data set you describe.

Something like:
xi: xtmixed score i.factor1*i.factor2 || subject: || subject:
R.factor1 || subject: R.factor2
may work, but ANOVA is using coding that makes comparisons to the
grand mean whereas xi is using 1-0 coding.
