Zero-inflated distributions are used to model count data that have many zero counts. For example, the zero-inflated Poisson distribution might be used to model count data for which the proportion of zero counts is greater than expected on the basis of the mean of the non-zero counts..

Zero-Inflated Poisson Regression With An Application to. The zero inflated Poisson regression as suggested by Lambert (1992) is fitted. Unless you have a sufficient number of zeros, there is no reason to use this model. The "zip.reg" is an internal wrapper function and is used for speed up purposes.
