Re: st: Re: Zero-inflated Negative Binomial models for Panel data

You might want to look at:

Dobbie, M.J. & Welsh, A.H. (2001) Modelling Correlated Zero-Inflated 
Count Data. Australian & New Zealand Journal of Statistics, 43, 431-444.

There are two different ways of modeling zi panel data. One uses a 
latent class structure, and the other an observed class, with truncated 
Poisson or Negative binomial. These authors chose the latter as more 
tractable for GEE type modeling.
