On age composition of dynamic heterogeneous populations

Ji Hwan Cha, Maxim Finkelstein

Research output: Contribution to journalArticlepeer-review

Abstract

Populations of items continuously manufactured and incepted into operation are characterized by the corresponding distribution of a random age at each instant of chronological time. In this study, we consider heterogeneous populations with lifetime distributions indexed by a frailty parameter. Two approaches to defining the age composition for the described populations are described and the corresponding stochastic comparisons are considered.
