mpcmp: Mean-parametrized Conway-Maxwell Poisson Regression

mpcmp

CRAN_Status_BadgeLifecycle: experimental Travis build status Codecov test coverage R build status

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.

Installation

Stable release on CRAN

The mpcmp package has been on CRAN since March 2019. You can install it from CRAN in the usual way:

install.packages("mpcmp")
library("mpcmp")

Development version on Github
