Heterogeneous risk models.

Abstract

"This paper briefly reviews the heterogeneous risk models in demography. With a specific model, it is shown that in a heterogeneous population, the marginal hazard need not be monotonic. Procedures described in the literature to recover individual hazards from marginal hazards without precise knowledge of structural parameters can lead to biased results. Strategies of parameter estimation and testing are discussed. The results are extended to [the] multistate life table."
