An examination of the effect of heterogeneity on the estimation of population size using capture-recapture data
捕获—再捕获数据中异质性对总体规模估计的影响
Part of the folklore of capture-recapture experiments is that ignoring heterogeneity of capture probabilities results in a downward bias. This has been based on experience and simulation studies but is often interpreted as being due to individuals with lower capture probabilities. Here estimating equation arguments are used to show that the effect on Horvitz–Thompson-type estimators of ignoring heterogeneity in capture-recapture experiments is to introduce a downward bias.…
