R2ucare: An r package to perform goodness-of-fit tests for capture–recapture models

Abstract

Assessing the quality of fit of a statistical model to data is a necessary step for conducting safe inference. We introduce R2ucare, an r package to perform goodness-of-fit tests for open single- and multi-state capture–recapture models. R2ucare also has various functions to manipulate capture–recapture data. We remind the basics and provide guidelines to navigate towards testing the fit of capture–recapture models. We demonstrate the functionality of R2ucare through its application to real data.
