Eric,

You could just run the nbreg with only the depvar, then with the full model.  After each do the following command:
di "log likelihood=" e(ll)

The pseudo R2 is just the proportional improvement in the -2ll

You can do this in one command after the nbreg:
di "pseudo R2=" (e(ll_0)-e(ll))/e(ll_0)

Hi all,

Does anybody know how to generate a Pseudo R-Square using the negative binomial model with the cluster option in Stata?

Any help on this would be much appreciated.

Thanks,

Eric
