Ageing and dependence are two important characteristics in reliability and survival analysis,
and they affect significantly the decision people make with regard to maintenance …

In summer of 2010, the first author (HL) visited the second author (XL) at Lanzhou University,
China, and chaired the dissertation defense for XL's two graduating doctoral students …

This paper conducts stochastic comparison on general residual life and general inactivity
time of (n− k+ 1)-out-of-n systems and investigates the stochastic behavior of the general …

In this paper we consider sufficient conditions in order to stochastically compare random
vectors of multivariate mixture models. In particular we consider stochastic and convex …

The purpose of this paper is to study the conditional inactivity time of failed components of a
coherent system consisting of n identical components with statistically independent lifetimes …

Multivariate dependence of spacings of generalized order statistics is studied. It is shown
that spacings of generalized order statistics from DFR (IFR) distributions have the CIS (CDS) …

Dispersion-type orders are introduced and studied. The new orders can be used to compare
the variability of the underlying random variables, among which are the usual dispersive …

Generalized order statistics introduced by Kamps [1995. A concept of generalized order
statistics. J. Statist. Plann. Inference 48, 1–23] provides a unified approach to a variety of …

Consider two random vectors X1 and X2 whose distributions are defined according to the
multivariate frailty approach, and let Xk, t=[Xk− t| Xk> t], k= 1, 2, be the corresponding vectors …

This paper studies the multivariate mixed proportional reversed hazard rate model having
dependent mixing variables. Stochastic comparison as well as aging properties in this …
