Abstract:

Capture-recapture estimation methods for closed wildlife population has been adapted by epidemiologists to estimate the size of a hidden or hard-to-reach population. The heterogeneity of capture probabilities on the estimation of population size using capture-recapture data is considered in this presentation. A generalized estimating equation approach to the estimating capturing probabilities is presented by considering the heterogeneity of the study population. Estimated probabilities, then serve as denominators for calculating the size of the population.
