title: An age and parity dependent model for birth intervals of non-contraceptive population.
abstract: "In this paper [an] age dependent model [for estimating birth intervals] is constructed which assumes that the women have already crossed the age of maximum fertility at the time of observation.  The parameters of the model are assumed to depend upon the parity."  This model is based on an earlier age-dependent model by the same authors and was designed to account for late marriage and high parity.  The model was applied to information on 203 married, non-contracepting women from a village in Haryana, India, collected in May and June of 1978. (SUMMARY IN FRE AND ITA)
