Abstract:
|
We introduce a semiparametric framework for capture-recapture experiments to extend the parametric capture-recapture models of Huggins (1989) to a broader range of applications. The resulting models for the capture probabilities include parametric components for some effects (e.g., time effect) and nonparametric components for both individual heterogeneity and behavioral response. In particular, the behavioral response is framed as a smooth function of an individual characteristic covariate, providing a new strategy for modeling. The method is evaluated in simulations and applied to several real datasets.
