A New Lifetime Model, Stochastic Orders and Kidney Infection Regression Model [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2021
We introduce a method to generate a new class of lifetime models based on the bounded distributions such that the defined models are exclusively a special case of the new class.

Cumulative Entropy of Past Lifetime for Coherent Systems at the System Level

open access: yesAxioms, 2023
This paper explores the cumulative entropy of the lifetime of an n-component coherent system, given the precondition that all system components have experienced failure at time t. This investigation utilizes the system signature to compute the cumulative

Stochastic comparisons on total capacity of weighted k-out-of-n systems with heterogeneous components

open access: yesStatistical Theory and Related Fields, 2022
This paper carries out stochastic comparisons on the total capacity of weighted k-out-of-n systems with heterogeneous components. The expectation order, the increasing convex/concave order and the usual stochastic order are employed to investigate ...

Dynamic Information Volatility Function

open access: yesStatistica, 2021
Liu (2007) discussed a new measure, known as the information volatility function to study the variability of the uncertainty contained in a probability distribution.

Many Roads to Synchrony: Natural Time Scales and Their Algorithms [PDF]

open access: yes, 2013
We consider two important time scales---the Markov and cryptic orders---that monitor how an observer synchronizes to a finitary stochastic process. We show how to compute these orders exactly and that they are most efficiently calculated from the epsilon-

Analysis of the Past Lifetime in a Replacement Model through Stochastic Comparisons and Differential Entropy

open access: yesMathematics, 2020
A suitable replacement model for random lifetimes is extended to the context of past lifetimes. At a fixed time u an item is planned to be replaced by another one having the same age but a different lifetime distribution. We investigate the past lifetime

Weighted survival functional entropy and its properties

open access: yesOpen Physics, 2023
The weighted generalized cumulative residual entropy is a recently defined dispersion measure. This article introduces a new uncertainty measure as a generalization of the weighted generalized cumulative residual entropy, called it the weighted ...

Two Sufficient Conditions for Convex Ordering on Risk Aggregation

open access: yesAbstract and Applied Analysis, 2018
We define new stochastic orders in higher dimensions called weak correlation orders. It is shown that weak correlation orders imply stop-loss order of sums of multivariate dependent risks with the same marginals.

On Some Aspects of Strong Risk Class and Associated Ordering

open access: yesJournal of Statistical Theory and Applications (JSTA), 2018
The paper opens up a new aging class and a new stochastic orders which is depend on risk class, that plays vital role in the reliability theory, finance topics, stochastic orders, and the economic theory.

Statistical Inference for a General Family of Modified Exponentiated Distributions

open access: yesMathematics, 2021
In this paper, a modified exponentiated family of distributions is introduced. The new model was built from a continuous parent cumulative distribution function and depends on a shape parameter.
