The Age-Specific Force of Natural Selection and Walls of Death

, 2008
W. D. Hamilton's celebrated formula for the age-specific force of natural selection furnishes predictions for senescent mortality due to mutation accumulation, at the price of reliance on a linear approximation.

Meenakshi’s-Gompertz Distribution and Its Properties

Journal of Probability and Statistical Science
The discussion revolves around the broader concept of exponential family distributions, exploring their applications in survival analysis and reliability engineering. Various distributions within this family, such as the Weibull, Rayleigh, and Gompertz distributions, are examined in terms of their suitability for modelling different phenomena ...

Linking period and cohort life-expectancy linear increases in Gompertz proportional hazards models [PDF]

In a Gompertz mortality model with constant yearly improvements at all ages, linear increases in period life expectancy correspond to linear increases in the respective cohort life expectancy.

The Gompertz Nadarajah-Haghighi (GoNH) Distribution Properties with Application to Real Data

Iraqi Journal for Computer Science and Mathematics
In this study, we propose a continuous statistical distribution consisting of four parameters based on the Gompertz family called the Gompertz Nadarajah-Haghighi (GoNH) distribution.

The Gompertz-Makeham distribution

, 1997
This work is about the Gompertz-Makeham distribution. The distribution has been applied plenty of times. The properties of the Gompertz-Makeham distribution investigated in this work are unimodality of the Gompertz-Makeham distribution and relationship between the median value and the mean residual life time of the Gompertz-Makeham distribution.

Gamma-Gompertz life expectancy at birth

Demographic Research, 2013
BACKGROUND The gamma-Gompertz multiplicative frailty model is the most common parametric modelapplied to human mortality data at adult and old ages. The resulting life expectancy hasbeen calculated so far only numerically.

The Gompertz distribution and its applications.

Genus, 1994
"In this paper we study the underlying Gompertz distribution and develop formulae for the moments and other characteristics of this useful but apparently unknown distribution. We find that the skewness and kurtosis of the distribution are fixed constants independent of the two distribution parameters, and this would appear to be the reason for the ...

The entropy-transformed Gompertz distribution: Distributional insights and cross-disciplinary utilizations

Kuwait Journal of Science
A novel two-parameter continuous model titled the entropy-transformed Gompertz (ETGPZ) distribution has been developed via the entropy transform. A new framework has been investigated and found to meet the criteria of the probability function.
