The present thesis analyzes several distribution characterizations
through their corresponding mean residual life or failure rate
function. These characterizations are obtained through relationships
between the mean residual lifetime function and the failure rate
function. The aim of the thesis is to study the concept of variance of
the residual life and single out the conditions under which the
variance of the residual life uniquely determines the distribution .This
function is expressed in terms of mean residual life and failure rate.
Numerical examples are provided to evaluate our results.
