Abstract

Chow attacks statistical power analysis on theoretical grounds. I argue that if significance testing is defensible, so is power analysis. A number of Chow's criticisms seem to suggest that power analysts are confused about certain fundamental issues. I claim that few power analysts make the mistakes Chow describes. Finally, I address Chow's claim that power analysis is irrelevant to NHSTP because it deals with a different issue.
