Mean residual life function wikipedia
WebJun 1, 2003 · INTRODUCTION In life testing situations, the expected additional lifetime given that a component has survived until time t is a function of t, called the mean residual life. … WebWe propose some estimation procedure for the mean residual life function with consistency and asymptotic normality on the left truncated and right censoring model. And then, the comparision with Kaplan-Meier estimator ignoring the left truncated effect and the small sample properities are investigated by asymptotic biases and M.S.E.`s through ...
