1993, for which he developed a variety of statistical software commands, including the first generalized linear model (GLM) program having a negative binomial regression family (1993). The negative binomial family is now incorporated into the GLM routines of all major commercial statistical software. Hilbe is regarded as having popularized negative binomial regression, particularly in the disciplines of biostatistics and health outcomes analysis. It is now a standard method used for modeling overdispersed count data. Hilbe's 2007 text, Negative Binomial Regression, was the first text specifically devoted to the model and its many variations. His 2014 Modeling Count Data is regarded as the first text on applied count models.
