Part of the Problem Books in Mathematics book series (PBM)


Demographers, actuaries, and vital statisticians, like others who use empirical materials, require models for the interpretation of their data. Their work begins with simple assumptions, necessarily highly abstract, and then proceeds to more realistic models that cannot avoid being more complex. This book starts with problems in which age, as well as most other features of real populations, is disregarded, and in which outcomes are taken as deterministic rather than stochastic. A brief introduction presents some of the mathematical concepts of this first preliminary chapter and defines the notation in which the problems are expressed.
