Log-Linear Models for Multiple Recaptures
This short stand-alone chapter is introduced mainly for historical reasons, though it has some interesting ideas and has had a resurgence for closed populations along with some new R software. For open and closed populations, the method consists of taking logarithms of the expected values of random variables, and then applying a two-way analysis of variance model where main effects and interactions are given biological interpretations. This is in contrast to applying logistic transformations to the population parameters. Residual plots are described for detecting heterogeneity and for pinpointing the occurrence of any temporary emigration and the presence of transients. The problem of fitting sub-models is discussed.
