Properties of proportional mean residual life model. (English) Zbl 1089.62120

Summary: The proportional mean remaining life (PMRL) model has been introduced in the literature by H. Zahedi [J. Stat. Plann. Inference 29, 221–228 (1991)] for modelling and analysing failure time data. In this paper, some properties of the PMRL model related to reliability analysis are investigated. Closure properties of a few aging classes and those of partial orders under the proportional mean residual life model are discussed.
