Model fit indices were averaged across 20 imputed datasets to include missing data. Results indicate that the negative binomial hurdle model had the best model fit.
Ordinary count negative binomial model had significantly better fit than the zero-inflated negative binomial model (Vuong test p = .12).
Ordinary count poisson model had significantly better fit than the zero-inflated poisson model (Vuong test p = .20).
