On Performance of Parametric and Distribution-free Models for Zero-inflated and Over-dispersed Count Responses
Zero-inflated Poisson (ZIP) and negative binomial (ZINB) models are widely used to model zero-inflated count responses. These models extend the Poisson and Negative Binomial (NB) to address excessive zeros in the count response. By adding a degenerate distribution centered at 0 and interpreting it a...
