title: [Forecasting cohort fertility rates by using an exponential function].
abstract: "Population forecasts based on cross sectional data do not allow for the variations in cohort fertility.  In this paper methods are developed to fit cohort fertility rates by an exponential function.  Out of a number of selected functions the Weibull-function shows the best fit.  For predicting cohort fertility pattern the parameter values can be derived from the forecasts of a small number of demographic statistics."  (summary in ENG)
