Stochastic Properties of the Weighted Hazard Rate Order [PDF]

Journal of Statistical Theory and Applications (JSTA), 2015
The hazard rate order between two weighted distributions with a given weight function is considered as a new stochastic order called weighted hazard rate order. The influences of biased sampling methods on properties of the hazard rate order are usefully

Joint weak hazard rate order under non-symmetric copulas [PDF]

Dependence Modeling, 2016
A weak version of the joint hazard rate order, useful to stochastically compare not independent random variables, has been recently defined and studied in [4]. In the present paper, further results on this order are proved and discussed.

Relative Orderings of Modified Proportional Hazard Rate and Modified Proportional Reversed Hazard Rate Models

Mathematics, 2023
In this paper, we identify several relative ordering properties of the modified proportional hazard rate and modified proportional reversed hazard rate models.

Hazard rate ordering of order statistics and systems [PDF]

Journal of Applied Probability, 2006
Let X = (X1, X2, …, Xn) be an exchangeable random vector, and write X(1:i) = min{X1, X2, …, Xi}, 1 ≤ i ≤ n. In this paper we obtain conditions under which X(1:i) decreases in i in the hazard rate order. A result involving more general (that is, not necessarily exchangeable) random vectors is also derived.

Preservation of hazard rate and relative average hazard rate orders in dependent series and parallel systems via Archimedean copulas

Journal of Inequalities and Applications
This paper develops a rigorous and unified preservation framework for hazard rate and relative average hazard rate stochastic orders in series and parallel systems with dependent component lifetimes. While preservation of hazard-rate-based orders is well

Stochastic comparisons of second-order statistics from dependent and heterogenous modified proportional hazard rate observations [PDF]

Statistics (Berlin), 2022
This manuscript studies the stochastic comparisons of the second-order statistics from dependent or independent and heterogeneous modified proportional hazard rate observations. Some sufficient conditions on the usual stochastic order of the second-order

Estimation for Exponentiated Generalized Xgamma Distribution from New General Class Based on Dual Generalized Order Statistics [PDF]

The Egyptian Statistical Journal, 2021
In this paper, the exponentiated generalized general class of distributions is introduced. Bayes estimators for the parameters, reliability and hazard rate functions are derived based on dual generalized order statistics.

Comparisons of Parallel Systems with Components Having Proportional Reversed Hazard Rates and Starting Devices

Mathematics, 2021
In this paper, we consider stochastic comparisons of parallel systems with proportional reversed hazard rate (PRHR) distributed components equipped with starting devices. By considering parallel systems with two components that PRHR and starting devices,
