Multiple Recaptures: Further Methods

Abstract

In the previous chapter, we introduced some models that have formed a historical basis for developments in capture–recapture, with some extensions. The subject has now taken off in a number of different directions that will be considered in this and the following chapters. Although the split with Chap. 5 is somewhat arbitrary, we begin this chapter with a useful concept in which a previous model can be reversed or read backward to enable one to consider recruitment. Then follows a powerful technique that is now very popular, and which uses the concept of hidden or latent variables where we use observed values to help us estimate hidden quantities. The method of estimating equations, originally developed for closed populations, is next as well as diversions into the use of time series and the modeling of stopover times.
