The mpcmp
package provides a collection of functions for estimation, testing and diagnostic checking for the mean-parametrized Conway-Maxwell Poisson (COM-Poisson) regression model for under- and over-dispersed count data of Huang (2017).
From version 0.3.0, mpcmp
supports log-linear mean models, also allows one to incorporate regression being linked to the dispersion parameter.
Work is progressing to include a zero-inflated Conway-Maxwell-Poisson model.
The mpcmp package has been on CRAN since March 2019. You can install it from CRAN in the usual way:
You can use the devtools package to install the development version of mpcmp from GitHub:
