A novel two-parameter discrete exponentiated exponential distribution with its neutrosophic extension: mathematical characterization and real-world count data modeling [PDF]

Frontiers in Big Data
This paper proposes and studies the Discrete Exponentiated Exponential (DEE) distribution, a new two-parameter discrete lifetime model obtained by applying the survival discretization technique to the exponentiated exponential distribution.

Multi-task survival modeling of dependent failure and reimplantation events in dental implants [PDF]

Scientific Reports
Dental implant failure and subsequent reimplantation are sequential clinical events influenced by complex, patient-specific factors. Traditional survival models often fail to capture the conditional dependencies in multi-stage outcomes.

A New Discrete Analogue of the Continuous Muth Distribution for Over-Dispersed Data: Properties, Estimation Techniques, and Application [PDF]

Entropy
We present a new one-parameter discrete Muth (DsMuth) distribution, a flexible probability mass function designed for modeling count data, particularly over-dispersed data. The proposed distribution is derived through the survival discretization approach.

Continuous and discrete-time survival prediction with neural networks [PDF]

Lifetime Data Analysis, 2021
AbstractDue to rapid developments in machine learning, and in particular neural networks, a number of new methods for time-to-event predictions have been developed in the last few years. As neural networks are parametric models, it is more straightforward to integrate parametric survival models in the neural network framework than the popular semi ...

Survival functions versus conditional aggregation-based survival functions on discrete space [PDF]

Information Sciences, 2022
In this paper we deal with conditional aggregation-based survival functions recently introduced by Boczek et al. (2020). The concept is worth to study because of its possible implementation in real-life situations and mathematical theory as well. The aim of this paper is the comparison of this new notion with the standard survival function.
