Some bivariate notions of IFR and DMRL and related properties
by
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.
