although the mean, variance and coefficient of variation of residual life which are based on the usual moments of the
residual life distribution are extensively used in reliability analysis. It has been establish ed in various theoretical and empirical
studies that the TL-moments have some advantages over the usual moments in many situations. Accordingly in the present paper we
study the properties of L-moments of residual life in the context of modeling lifetime data, characterizing life distributions and other applications. The role of certain quantile functions and quantile-based concepts in reliability analysis are also investigated. |
