The Performance of Mixture Models in Heterogeneous Closed Population Capture-Recapture

Dorazio and Royle (2003, Biometrics 59, 351-364) investigated the behavior of three mix­ture models for closed population capture-recapture analysis in the presence of individual heterogeneity of capture probability. Their simulations were from the beta-binomial distribution, with analyses from the betabinomial, the logit-normal, and the finite mixture (latent class) models. In this response, simulations from many different distributions give a broader picture of the relative value of the beta-binomial and the finite mixture models, and provide some preliminary insights into the situations in which these models are useful.
