Capture-recapture experiments are commonly used to estimate the size of a closed population. However, the associated estimators of the population size are well known to be highly sensitive to misspecification of the capture probabilities. To address this, we present a general semiparametric framework for the analysis of capture-recapture experiments when the capture probability depends on individual characteristics, time effects and behavioural response. This generalizes well-known general parametric capture-recapture models and extends previous semiparametric models in which there is no time dependence or behavioural response. The method is evaluated in simulations and applied to two real data sets. © 2012 Australian Statistical Publishing Association Inc.
