Building on the work by Hardin (Stata Journal 2: 253–266), this note shows how the calculation of the Murphy-Topel variance estimator for two-step models can be simplified in Stata by using the scores option of predict. Copyright 2006 by StataCorp LP.

In this article, we describe the gmnl Stata command, which can be used to fit the generalized multinomial logit model and its special cases. Copyright 2013 by StataCorp LP.
