Zero Inflated Negative Binomial. Zero-Inflated Negative Binomial Regression Introduction The zero-inflated n egative binomial ZINB regression is used for count data that exhibit overdispersion and excess zeros. The Poisson hurdle model was introduced by John Mullahy.
The predictors can be different for the two models. Zero observation can come from either distribution non-zero ones only from the NB. Normal Poisson binomial negative-binomial and beta the data set is referred to as zero inflated Heilbron 1994.
