Power Calculations for Logistic Regression

Stata (v.19) now include a new command -- power logistics -- that computes sample size, power, or effect size for testing a coefficient of interest in a logistic regression model. A brief description is here and, insofar as a healthy swath of empirical legal studies involves logit (or probit) estimations (e.g., judge outcome/vote studies), this new command may make life a bit easier for some.
