A multivariate Gompertz-type distribution

Journal of Applied Statistics, 2001
The Gompertz distribution has many applications, particularly in medical and actuarial studies. However, there has been little recent work on the Gompertz in comparison with its early investigation. The problem of finding and analysing a bivariate (or multivariate) Gompertz distribution is of interest and the focus of this paper.

On the Inverse Power Gompertz Distribution

Annals of Data Science, 2020
In this article, we introduce inverse Power Gompertz distribution with three parameters. Some statistical properties are presented such as hazard rate function, quartile, probability weighted (moments), skewness, kurtosis, entropies function, Bonferroni and Lorenz curves and order statistics.

Gompertz in Context: The Gompertz and Related Distributions

2001
A model often used in mortality analysis and forecasting is the Gompertz model. The model is attractive because the mathematical specification is consistent with theories of ageing. Other models that are used less often share some of the useful features of the Gompertz model. Furthermore, the Gompertz can be approached as a member of families of models

Gompertz-Lindley distribution and associated inference

Communications in Statistics - Simulation and Computation, 2019
In this paper, we present a Gompertz-Lindley distribution obtained by mixing the frailty parameter of Gompertz distribution by Lindley distribution.

INVERTED GOMPERTZ DISTRIBUTION: PROPERTIES AND ESTIMATION

المجلة العلمیة لقطاع کلیات التجارة, 2012
The inverted Gompertz distribution,and some of its properties are investigated.  The distribution of the order statistic of the inverted Gompertz  distribution and some special cases are presented. Transformed distributions of this distribution are derived.

MAXWELL-GOMPERTZ DISTRIBUTION: PROPERTIES AND APPLICATIONS

This paper proposed a three parameter Maxwell-Gompertz distribution as an extension of Gompertz distribution. Some statistical properties of the distribution such as moments, survival and hazard functions, quantile function, Rényi entropy and order statistics were derived. Maximum likelihood method was used to estimate the model parameters.

Bayesian Approximation Techniques for Gompertz Distribution

2019
We presented approximate to Bayesian integrals of Gompertz distribution depending upon numerical integration and simulation study and showed how to study posterior distribution by means of simulation study. From the findings of above tables (1, 2, 3, 4) it has been found that the large sample distribution could be improved when prior is taken into ...
