On stochastic comparisons of largest order statistics in the scale model

Subhash C. Kochar, Nuria Torrado

Let $X_{λ_{1}}, X_{λ_{2}}, \dots, X_{λ_{n}}$ be independent nonnegative random variables with $X_{λ_{i}} \sim F (λ_{i} t)$ , $i = 1, \dots, n$ , where $λ_{i} > 0$ , $i = 1, \dots, n$ and $F$ is…

Stochastic order relations among parallel systems from Weibull distributions

Nuria Torrado, Subhash C. Kochar

In this article, we focus on stochastic orders to compare the magnitudes of two parallel systems from Weibull distributions when one set of scale parameters majorizes the other. Th…

Order restricted inference for comparing the cumulative incidence of a competing risk over several populations

Hammou El Barmi, Subhash Kochar, Hari Mukerjee

There is a substantial literature on testing for the equality of the cumulative incidence functions associated with one specific cause in a competing risks setting across several p…
