Fit Conway-Maxwell Poisson (COM-Poisson or CMP) regression models
to count data (Sellers & Shmueli, 2010) <doi:10.1214/09-AOAS306>. The
package provides functions for model estimation, dispersion testing, and
diagnostics. Zero-inflated CMP regression (Sellers & Raim, 2016)
<doi:10.1016/j.csda.2016.01.007> is also supported.
