Abstract
When modeling the hazard of entry into marriage, the non-mono-
tonic dependence on age needs to be taken into account. In this paper,
nonlinear discrete-time hazard models based on a bell-shaped func-
tion are proposed, in which the support of the hazard function, the
maximum hazard and the age of maximum hazard are estimated di-
rectly. Starting in the proportional hazards framework, the baseline
hazard model proposed by Blossfeld and Huinink (American Journal
of Sociology, 1991) is extended to allow estimation of the support of
