# Hierarchical Multiple Regression Post-hoc Statistical Power Calculator

Compute the observed power for a hierarchical regression study. The calculator computes the observed power for a significance test of the addition of a set of predictor variables B to the hierarchical model, over and above another set of predictor variables A. Knowing whether a model had enough power to detect an expected effect may be useful for analytics studies that rely on hierarchical regression.
