RELOGIT: Stata module to perform Rare Event Logistic Regression

relogit is a suite of programs for estimating and interpreting logit results when the sample is unbalanced (one outcome is rarer than the other) or has been selected by a rule correlated with the dependent variable. RELOGIT estimates the same logit model as the logit command, but with an estimator that give lower mean square error in the presence of rare events data for coefficients, probabilities, and other quantities of interest.
