摘要：In the present work we propose a study of the proportional mean residual life model
using quantile functions instead of distribution functions employed in the traditional
approach. Through various quantile-based reliability concepts ageing properties of the
model are discussed. We present characterizations of the proportional mean residual
life model by properties of measures of uncertainty in the residual lives of the variables.
Some stochastic order properties relating to the model are also derived.
