Hi all. I want to run a power analysis to verify the necessary sample size to adequately run an experiment with four experimental conditions (3 experimental groups plus a control group). It is not a factorial experiment.
Type of power analysis: a priori
Statistical test: ANOVA fixed effects, omnibus, one-way
Effect size: 0.1
alpha error prob: .05
1-beta error prob: .95
Number of groups: 4
Does Stata have a command to run a power analysis in this case?
Thank you
