Some bivariate notions of IFR and DMRL and related properties
Bruno Bassan, Subhash Kochar and Fabio Spizzichino
Recently Bassan and Spizzichino (1999) have given some new concepts of multivariate aging for exchangeable random variables, such as a special type of bivariate IFR, by comparing distributions of residual lifetimes of dependent components of different ages. In the same vein, we further study some properties of concepts of IFR in the bivariate case. Then we introduce concepts of bivariate DMRL aging and we develop a treatment that parallels the one developed for bivariate IFR. For both concepts of IFR and DMRL, we analyze a weak and a strong version, and discuss some of the differences between them.
