What is difference between "structural zeros and sampling zeros?
What is difference between zero-inflated and hurdle model?
How to apply zero inflated Poisson (ZIP) model in R?
How to apply zero inflated Negative Binomial (ZINB) model in R?
How to interpret results of count models?
How do we know whether to apply a zero inflated model or not?
