We provide here the code to illustrate CR models with individual heterogeneity, namely CR multistate, random-effect and finite-mixture models. These are 3 appendices for a paper submitted to Oikos for a special issue. The paper is entitled: 'Individual heterogeneity and capture-recapture models: what, why and how? ' and is co-authored with Emmanuelle Cam and Jean-Michel Gaillard.
Using the same simulated data, we illustrate three different ways of incorporating individual heterogeneity in capture-recapture models.
A. a Frequentist approach using maximum likelihood methods implemented in MARK called from R using package Rmark:
