These extensions address departures from assumptions underpinning the Poisson model. The negative binomial distribution is a widely used count model that can, to some extent, address some of the violations of assumptions of Poisson models. Because of its flexibility, it is commonly used in ...
1. Negative Binomial Regression: Independent variables are the log of previous three independent variables. And dependent one remains as before. Although they don't have to be like normal distribution, I just opportunistically tried so. (Actually) Luckily, the model works: Table 1. Negative ...

We study inference and diagnostics for count time series regression models that include a feedback mechanism. In particular, we are interested in negative binomial processes for count time series. We study probabilistic properties and quasi-likelihood estimation for this class of processes. We show th...

Given that the dependent variable is a count variable, the likely candidates are count regression models. My fear is with how to deal with unobserved heterogeneity and sample selection issues if I limit my analysis to the non-zero visits. If I use the standard two-part or hurdle model, I ...
