zinb estimates Zero Inflated Negative Binomial models on count data. This model allows for "excess zeros" in count models under the assumption that the population is characterized by two regimes, one where members always have zero counts, and one where members have zero or positive counts. The ...

I am working with a dataset that contains counts of the number oftimes that youth in the sample engage in self-harming behaviors(such as cutting). My co-authors and I are interested in using thezero-inflated negative binomial models because (a) we have a samplethat has about 74% zeroes ...
