st: zero-inflation in xtgee

[D Ma <lrpwhn@yahoo.com>]

Dear Colleagues,

I am running a xtgee model like this:

xtgee y x1 x2 x3 ... ,family(nb) link(log) vce(robust) nolog

Since there are lots of zeros in the dependent count varaible y, I want to use a zero-inflated model.  Nonetheless, the xtgee command in stata doesn't seem to have that option.  Do you have any suggestions?

Thanks!

Best regards,

Dali
