"The general solution of related estimation and inference problems we can specify as application of Fisher scoring algorithm for maximum likelihood estimators with constraints (in Section 2).... Application to regional fertility patterns (in Section 3) yields the simultaneous solutions of tasks about structural fertility differentiations which have not been presented with correct stochastic evaluation.... The functions used for approximations of age-specific fertility schedules coincide with the most usual types of curves described in demographic literature...." (SUMMARY IN CZE)
