A stochastic comparison study for the smallest and largest ordered statistic from Weibull-G and Gompertz Makeham distribution
Madhurima Datta, Nitin Gupta
In this paper, we have discussed the stochastic comparison of the smallest and largest ordered statistic from independent heterogeneous Weibull-G random variables and Gompertz Make…

Usual stochastic ordering results for series and parallel systems with components having Exponentiated Chen distribution
Madhurima Datta, Nitin Gupta
In this paper, we have discussed the usual stochastic ordering relations between two systems. Each system consists of n mutually independent components. The components follow Expon…

Stochastic comparison study of the general family of PHR and PRHR distributions
Madhurima Datta, Nitin Gupta
In this paper, we have obtained conditions on parameters that result in dispersive ordering and star ordering among two unequal sets of random variables from Proportional hazard ra…
