Retrospective power analysis using external information

Abstract

The present article proposes an ideal that every statistical analysis be followed up with a power calculation to better understand the inference from the data. As the quotations above illustrate, however, our suggestion contradicts the advice of many respected statisticians. Our resolution of this apparent disagreement is that we perform retrospective power analysis in a different way and for a different purpose than is typically recommended in the literature.
