About

Maintained by Jonathan WoodFirst published 2026-01-191 releasesCRAN page ↗

An implementation of multiple regression models for count data. These include various forms of the negative binomial (NB-1, NB-2, NB-P, generalized negative binomial, etc.), Poisson-Lognormal, other compound Poisson distributions, the Generalized Waring model, etc. Information on the different forms of the negative binomial are described by Greene (2008) doi:10.1016/j.econlet.2007.10.015. For treatises on count models, see Cameron and Trivedi (2013) doi:10.1017/CBO9781139013567 and Hilbe (2012) doi:10.1017/CBO9780511973420. For the implementation of under-reporting in count models, see Wood et al. (2016) doi:10.1016/j.aap.2016.06.013. For prediction methods in random parameter models, see Wood and Gayah (2025) doi:10.1016/j.aap.2025.108147. For estimating random parameters using maximum simulated likelihood, see Greene and Hill (2010) doi:10.1108/S0731-9053(2010)26; Gourieroux and Monfort (1996) doi:10.1093/0198774753.001.0001; or Hensher et al.

Install

R (CRAN)Ubuntu (r2u)openSUSE (OBS)

install.packages("flexCountReg", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-flexcountreg

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled.

bspm (used by r2u) also needs make: sudo apt install make

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-flexCountReg

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed).
