DOI: 10.1007/s11749-018-0581-7
Abstract: In this paper, we consider the classical finite mixture model, which is an effective tool for modeling lifetime distributions for random samples from heterogeneous populations. We discuss new results on stochastic comparison for two finite… read more here.

DOI: 10.1017/jpr.2018.30
Abstract: Abstract For many practical situations in reliability engineering, components in the system are usually dependent since they generally work in a collaborative environment. In this paper we build sufficient conditions for comparing two coherent systems… read more here.

DOI: 10.1017/jpr.2019.89
Abstract: Abstract We consider coherent systems with independent and identically distributed components. While it is clear that the system’s life will be stochastically larger when the components are replaced with stochastically better components, we show that,… read more here.

DOI: 10.1017/s0269964823000104
Abstract: In this paper, we establish some stochastic comparison results for largest claim amounts of two sets of independent and also for interdependent portfolios under the setup of the proportional odds model. We also establish stochastic… read more here.

DOI: 10.1080/03610926.2018.1435806
Abstract: ABSTRACT This paper deals with series and parallel systems of dependent components equipped with starters. We study the hazard rate order, the dispersive order and the usual stochastic order of system lifetimes in the context… read more here.

DOI: 10.1080/03610926.2020.1861299
Abstract: The variance of the log-likelihood function, which is called varentropy, is a measure of the concentration of information content around the Shannon entropy. This measure is widely applied in finit... read more here.
