WebThe empirical mean residual life plot is the locus of points \left (u,\frac {1} {n_u} \sum\nolimits_ {i=1}^ {n_u} (x_ { (i)} - u) \right) (u, nu1 ∑i=1nu (x(i) −u)) where x_ { (1)}, \dots, x_ { (n_u)} x(1),…,x(nu) are the n_u nu observations that exceed the threshold u u. WebJan 1, 1988 · Introduction and summary The mean residual life (MRL) has been used as far back as the third century A.D. (cf. Deevey (1947) and Chiang (1968)). In the last two decades, however, reliabilists, statisticians, and others have shown intensified interest in the MRL and derived many useful results concerning it. WebThe mean residual life function of the weighted distribution is (4.52) From (4.52), we obtain (b). Theorem 4.28 If X is IFR (DFR) and is increasing and concave (decreasing and convex), then is IFR (DFR). Proof From (4.51), we have by the … man weave unit installer
