Greetings,

I am conducting analyses using zero-inflated negative binomial regression. Unlike regular negbin output, ZIP models do not produce a Pseudo R-Squared statistic. I would like to know if there is a Stata command whereby I can produce a Pseudo R-squared statistic, or its equivalent, to determine model fit in a ZIP model.

Many thanks,

Josh
