countreg: Count Data Regression

Regression models for count data, including zero-inflated, zero-truncated, and hurdle models as well as generalized count data regression. Drivers for combination with flexmix and mboost are also provided. For (graphically) assessing the goodness of fit for (regression) models, rootograms and quantile residuals are available.
