โฆ Synopsis
In addition to the CDF or density function, the failure rate and mean residual life functions are the other important functions that can be used to characterize a lifetime. In the literature, much work on the properties of these quantities has been done. This paper points out and corrects some errors in the literature by giving a counterexample and new proofs. Moreover, it gives a more complete discussion on the shape of the mean residual life function when the associated failure rate function has a roller-coaster shape. It also discusses the crossing properties of two mean residual life functions in detail, when the associated failure rate functions have several crossing points.

A direct approach to measure uncertainty in the residual life time distribution has been initiated by Ebrahimi (1996, Sankhya Ser. A 58, 48-57) and explored further by Ebrahimi and Pellerey (1995) and Ebrahimi and Kirmani (1996). In this paper, some new properties of the proposed measure in connecti
