EXPONENTIALITY WITHIN CLASS ℒ AND STOCHASTIC EQUIVALENCE OF LAPLACE ORDERED SURVIVAL TIMES
Published online by Cambridge University Press: 01 April 1999
Abstract
We obtain necessary and sufficient moment conditions for exponentiality among all class ℒ aging distributions. This result, which solves an open problem, is derived as a consequence of the answer to a more general question of investigating conditions for stochastic equivalence of Laplace ordered nonnegative r.v.'s and its ramifications.
