The COMMultReg package demonstrates the Conway-Maxwell Multinomial (CMM) distribution and regression model from the paper:

Darcy Steeg Morris, Andrew M. Raim, and Kimberly F. Sellers (2020). A Conway-Maxwell-multinomial distribution for flexible modeling of clustered categorical data. Journal of Multivariate Analysis, 179:104651. https://doi.org/10.1016/j.jmva.2020.104651.

To install the package from Github, run:

library(devtools)
install_github("andrewraim/COMMultReg")

Some examples are provided in the inst folder, including:

1. A Shiny app to visualize the Conway-Maxwell Binomial distribution.
2. A Shiny app to visualize trinomial CMM, as in Figure 2 of the paper.
3. Fitting CMM to the pollen dataset, as in section 6 of the paper.
4. Fitting CMM to the gator dataset, as in the supplement of the paper.
