R help - Sep 2007 - power calculation for repeated measures ANOVA?

Is there a way to calculate power for repeated
measures ANOVA (2 groups x 7 observations)? I have
searched all over, but all I can find is
power.anova.test, but that would not give accurate
results, right?

Thanks,
Matt Bridgman

Mind a book reference instead of a software reference?

Look for Bausell and Li's "Power Analysis for Experimental
Research"
-- cookbook style power calculations, but has explicit RM ANOVA.

I can answer any question.
"I don't know" is an answer.
"I don't know yet" is a better answer.

G*Power 3 is free software for Mac and PC, see
