    Mean Residual Life

    Hi, I've been tasked with solving the mean residual life given the density function f(x) and the survival function S(x) I think mean residual life can be calculated by: mrl(x)=[∫(t-x)f(x)dt]/S(x)] or mrl(x)=∫S(t)dt/S(x) the problem is, f(x) contains the gamma function and I don't...
