# SSPECIALREG: Stata module to estimate binary choice model with discrete endogenous regressor via special regressor method

*Christopher Baum* ()

Statistical Software Components from Boston College Department of Economics

**Abstract:**
sspecialreg estimates a binary choice model that includes one or more endogenous regressors using Lewbel and Dong's special regressor method (Econometric Reviews, 2015; Journal of Econometrics, 2000). This assumes that the model includes a particular 'special regressor', V, that is exogenous and appears additively in the model. It must be continuously distributed with a large support. A special regressor with thick tails (greater kurtosis) will be more useful as a special regressor. This method has advantages over the linear probability model (estimated with OLS or IV), maximum likelihood and control function methods. The xtspecialreg command estimates the model in a panel data setting, with the data xtset or tsset.
