I have researched some of the documentations but couldn't find a reference to that. Does such a model exist at all in the literature? Zeroinflation is a two part (mixture) model.Zeroinflated negative binomial regression is for modeling count variables with excessive zeros and it is usually for overdispersed count outcome variables. Furthermore, theory suggests that the excess zeros are generated by a separate process from the count values and that the excess zeros stata zero-inflated negative binomial panel

Jan 17, 2018 ZeroInflated Negative Binomial Model for Panel Data. This model assumes that the zeros are a mixture of two data generating processes. If your theory does not point into this direction, I would be reluctant to jump to such model. That said, I am not aware of a zeroinflated version of count models for panel data. Someone else might know more than I do. Best Daniel.

Does Stata support Zeroinflated Negative Binomial models for Panel data? I have researched some of the documentations but couldn't find a reference to that. Mar 10, 2010 Greetings I was not able to find anything that can do this within Stata (which is not to say that it cannot be done). It is possible that this might be doable using gllamm (see findit gllamm). Also, I believe you could do this s a multilevel negative binomial regression using Mplus. Although I cannot find an Mplus example like this, it would combine these elements**stata zero-inflated negative binomial panel** Mar 11, 2010 gllamm does not support the negative binomial family. However since the negative binomial model is the Poission model with a gamma random effect (integrated over), you may be able to get some leverage out of Poisson family.
