In this article, we describe the switch_probit command, which implements the maximum likelihood method to fit the model of the binary choice with binary endogenous regressors. Copyright 2011 by StataCorp LP.

This article describes the new Stata command xml_tab, which outputs the results of estimation commands and Stata matrices directly into tables in XML format. The XML files can be opened with Microsoft Excel or OpenOffice Calc, or they can be linked with Microsoft Word files. By using XML,...

This article describes the movestay Stata command, which implements the maximum likelihood method to fit the endogenous switching regression model. Copyright 2004 by StataCorp LP.

This article describes the plreg command, which implements the difference-based algorithm for fitting partial linear regression models. Copyright 2006 by StataCorp LP.

We discuss the estimation of a regression model with an ordered- probit selection rule. We have written a Stata command, oheckman, that computes two-step and full-information maximum-likelihood estimates of this model. Using Monte Carlo simulations, we compare the performances of these...
