COMPoissonReg (version 0.8.1)

Conway-Maxwell Poisson (COM-Poisson) Regression

Description

Fit Conway-Maxwell Poisson (COM-Poisson or CMP) regression models to count data (Sellers & Shmueli, 2010) . The package provides functions for model estimation, dispersion testing, and diagnostics. Zero-inflated CMP regression (Sellers & Raim, 2016) is also supported.
