On arbitrarily underdispersed discrete distributions

A Huang - The American Statistician, 2023 - Taylor & Francis
We survey a range of popular generalized count distributions, investigating which (if any)
can be arbitrarily underdispersed, that is, its variance can be arbitrarily small compared to its …

[HTML][HTML] Zero-inflated Conway-Maxwell Poisson distribution to analyze discrete data

SZ Sim, RC Gupta, SH Ong - The international journal of biostatistics, 2018 - degruyter.com
In this paper, we study the zero-inflated Conway-Maxwell Poisson (ZICMP) distribution and
develop a regression model. Score and likelihood ratio tests are also implemented for …
