Topp-Leone Gompertz Distribution: Properties and Applications

Journal of Data Science, 2021
This paper proposes the Topp-Leone Gompertz distribution; an extension of the Gompertz distribution for modeling real life time data. The new model is obtained by transforming the cumulative distribution function of the Gompertz random variable, while ...

Comparative Study with Applications for Gompertz Models under Competing Risks and Generalized Hybrid Censoring Schemes

Axioms, 2023
In reliability and survival analysis, the time-to-failure data play an important role in the development of the reliability and life characteristics of the products. In some cases, these kinds of data are modeled using a competing risks model.

Determination of the most appropriate method for extrapolating overall survival data from a placebo-controlled clinical trial of lenvatinib for progressive, radioiodine-refractory differentiated thyroid cancer [PDF]

, 2016
Background: Cost-effectiveness models for the treatment of long-term conditions often require information on survival beyond the period of available data.

New Modified Gompertz Probability Distribution With Flexible Hazard Functions

Journal of Probability and Statistics
This paper introduces a new probability model called the modified Gompertz distribution from the base Gompertz distribution by combining its hazard function with first and second degree polynomial (linear and quadratic) functions.

The Modified Beta Gompertz Distribution: Theory and Applications

Mathematics, 2018
In this paper, we introduce a new continuous probability distribution with five parameters called the modified beta Gompertz distribution. It is derived from the modified beta generator proposed by Nadarajah, Teimouri and Shih (2014) and the Gompertz ...

Simulations of a mortality plateau in the sexual Penna model for biological ageing [PDF]

, 2005
The Penna model is a strategy to simulate the genetic dynamics of age-structured populations, in which the individuals genomes are represented by bit-strings.

Statistical Inference for the Gompertz Distribution Based on Adaptive Type-II Progressive Censoring Scheme

Mathematical Problems in Engineering, 2022
The topic of estimating the parameters of Gompertz distribution using an adaptive Type-II progressively censored data are described in this paper. The unknown parameters, the reliability, and the hazard functions are estimated using maximum likelihood ...

The Exponentiated Generalized Extended Gompertz Distribution

, 2021
This paper presents a new generalization of the extended Gompertz distribution. We defined the so-called exponentiated generalized extended Gompertz distribution, which has at least three important advantages: (i) Includes the exponential, Gompertz ...
