Abstract

The approach to mortality estimation in chapter 2 was based on the formalism of stage structure models (see for example Gurney et. al. 1983), but it was shown that estimators based on such models are prone to instability when applied to less than perfect data. Therefore we now consider a less restrictive approach based directly on the von Foerster equation (see for example Nisbet and Gurney 1982, chapter 3); our aim is to produce an estimate of the age-specific death rate which is consistent with stage abundance data from a population, but which displays stability with respect to observational errors. The end point of our work is a rather elaborate recipe, detailed in section 4.8.
