I am trying to do a power analysis for an experiment that will have aAl Feiveson wrote a nice little Stata Journal article on determining power in any given model by simulation. This is most flexible.

2-level between subjects factor and then a 3-level within subjects factor

(i.e., baseline, intervention, baseline) for an ANOVA analysis. Could anyone

give me some advice about this. I looked at several packages (sampsi,

powercal, etc.) and am having difficulty figuring it out.

The Stata Journal 2 Number 2

Power by simulation: This paper describes how to write Stata programs to estimate the power of virtually any statistical test that Stata can perform. Examples given include the t test, Poisson regression, Cox regression, and the nonparametric rank-sum test.
