In general, after using an estimation command -foo- typing -help foo
postestimation- shows what is available built in to official Stata. If
-foo- is -nbreg- then -estat gof- is not available. It's either what
Is available, or anything appropriate that is user-written, as Owen's
answer implies.

>> I'm modeling count data that shows signs of overdispersion so I'm using Negative Binomial instead of Poisson regression. I would like to check the goodness of fit of the overall model. Is there an equivalent command to estat gof that works after running "nbreg (variables)" to obtain the goodness-of-fit chi-squared test? (I'm getting "invalid sub command" when I try to run estat gof with nbreg).
