Abstract

This paper reconsiders Coale and Trussell's (1974) specification of model fertility schedules by age. It formally presents model fertility schedules within the framework of categorical data analysis. Specifically, births are assumed to follow an independent Poisson distribution for each age interval of each population. Identification and estimation problems are discussed. It shows that the Coale-Trussell specification corresponds to Goodman's (1979) log-multiplicative model. Following Goodman's algorithm, the paper simultaneously estimates Coale and Trussell's υ (age), m, and M through an iterative maximum likelihood procedure. This is demonstrated with the same data that were used in Coale and Trussell's article. The new estimates are superior to those of Coale and Trussell according to an array of conventional goodness-of-fit criteria.
