The total numbers of births and deaths in a population are given at discrete equispaced time intervals. It is assumed that the birth and death rates depend on age, the population size and possibly time. Further it is assumed that the rates fluctuate randomly from individual to individual. The problem is to estimate average birth and death rates and the age structure of the evolving population. Results are presented for a population of sheep blow-flies maintained under stable conditions for a two year period (361 observations) by A. J. Nicholson.
