Power Analysis repeated measures ANOVA with more than 2 groups unbalanced design

[Ann Chen]

Hi,

Does anyone know whether Stata can do power analysis for repeated measures ANOVA with unbalanced design (3 groups)? I wanted to specify the % of the group sizes (60%, 20%, 20%) for the analysis. I read the document power repeated — Power analysis for repeated measures analysis of variance, but it only presented two groups examples.

I appreciate any comments and helps.

Thanks,
Ann
