An investigation of the relation between online and offline violence: methodological and theoretical considerations [PDF]

open access: yesFrontiers in Psychology
IntroductionResearch focusing on whether exposure to “online” violence via social media (exposure to violent content, such as videos of beatings or fights) predicts the use of physical “offline” violence (from hitting and threatening someone to violence ...

Causal Inference in Threshold Regression and the Neural Network Extension (TRNN)

open access: yesStats, 2023
The first-hitting-time based model conceptualizes a random process for subjects’ latent health status. The time-to-event outcome is modeled as the first hitting time of the random process to a pre-specified threshold.

Hitting statistics from quantum jumps [PDF]

open access: yesQuantum, 2017
We define the hitting time for a model of continuous-time open quantum walks in terms of quantum jumps. Our starting point is a master equation in Lindblad form, which can be taken as the quantum analogue of the rate equation for a classical continuous ...

An Imperfect Repair Model with Delayed Repair under Replacement and Repair Thresholds

open access: yesMathematics, 2022
Based on the extended geometric process, a repair replacement model of a degradation system is studied, in which the delayed repair time depends on the working time after the last repair. Replacement and repair thresholds describe when the system will be

Regression Models for Lifetime Data: An Overview

open access: yesStats, 2022
Two methods dominate the regression analysis of time-to-event data: the accelerated failure time model and the proportional hazards model. Broadly speaking, these predominate in reliability modelling and biomedical applications, respectively.

Multivariate Threshold Regression Models with Cure Rates: Identification and Estimation in the Presence of the Esscher Property

open access: yesStats, 2022
The first hitting time of a boundary or threshold by the sample path of a stochastic process is the central concept of threshold regression models for survival data analysis.

Antagonistic One-To-N Stochastic Duel Game

open access: yesMathematics, 2020
This paper is dealing with a multiple person game model under the antagonistic duel type setup. The unique multiple person duel game with the one-shooting-to-kill-all condition is analytically solved and the explicit formulas are obtained to determine ...
