Mean residual life plot
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 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.

If the exceedances of a threshold u 0 are generalized Pareto, the empirical mean residual life plot should be approximately linear for u > u 0. WebSep 13, 2024 · The following plot shows an example of a fitted values vs. residual plot that displays non-constant variance: Notice that the spread of the residuals grows larger and larger as the fitted values increase. This is a typical sign of non-constant variance.
