Does Stata support Zero-inflated Negative Binomial models for Panel data?I have researched some of the documentations but couldn't find a reference to that. Thanks * * For searches and help try: *http://www.stata.com/help.cgi?search*http://www.stata.com/support/statalist/faq*http://www...
Hello all, The reference entries for zero-inflated poisson and negative binomial are quite scant (at least to me). I didn't find much either in the list archive or Stata Journal archives. There is an example on:http://www.ats.ucla.edu/stat/stata/output/Stata_zinb.htm.; The UCLA examp...
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 on a model with a count outcome and trying to figure out which has a better fit- negative binomial or zero inflated negative binomial. (Poison definitely doesn’t fit well due to over dispersion). While the AIC is better for zero inflated models, the BIC tends to point towa...

Zero-inflated Poisson and zero-inflated negative binomial regression models have been proposed for data sets that result into too many zeros. Recently, the zero-inflated generalized Poisson regression model is defined as a good alternate... F Famoye,KP Singh - 《Advances & Applications in Statisti...
They also proposed a zero-inflated Gamma model for excess zeroes which were dealt with in probit regression. Most of the existing literature on LGD modelling in the consumer and corporate credit risk domains has focused on modelling the LGD distribution directly. However, this distribution is known...
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 ...
