Poisson-Tweedie mixed-effects model: flexible modelling of longitudinal overdispersed counts

What is ptmixed

ptmixed is an R package that allows to estimate the Poisson-Tweedie generalized linear mixed model presented in Signorelli, Spitali and Tsonaka (2021). Poisson-Tweedie mixed-effects model: a flexible approach for the analysis of longitudinal RNA-seq data. Statistical Modelling, 21 (6), 520-545. DOI: 10.1177/1471082X20936017.

About this repository

This repository contains data and code to reproduce the simulations presented in Signorelli, Spitali and Tsonaka (2021).

How to use ptmixed

ptmixed can be downloaded from CRAN. Installation of the package in R can be done through the command

install.packages('ptmixed')

If you encounter problems with packages on which ptmixed depends, you may alternatively install the package using BiocManager:

if (!require("BiocManager", quietly = TRUE)) install.packages("BiocManager")
BiocManager::install('ptmixed')
