Re: st: Zero-inflated poisson/negbin-models for PANEL data

[Christer.Thrane@hil.no]

Hi,

It seem as if there is no such procedure.

One solution is to use the traditional zero-inflated models with the
-cluster- and -robust- option.

Best regards,

Christer

Hi Christer,

     I am on the Stata list and saw your email. I never saw if you received
a response to your query. It is something I'm interested in as well. If you
have any further information, I'd appreciate hearing from you about it.

                               Sincerely,
                               Michael
