Estimation of the Gompertz distribution’s parameters under folded ranked set sampling

Sigma Journal of Engineering and Natural Sciences
In the current paper, estimation of the unknown parameters of the Gompertz distribution is considered using different methods of estimation based on simple random sampling (SRS), ranked set sampling (RSS), and folded ranked set sampling (FRSS).

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.

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

Properties and Applications of the Gompertz Distribution

International Journal of Mathematical Sciences and Optimization: Theory and Applications, 2023
The importance of statistical distributions in describing and predicting real world events cannot be over-emphasized. The Gompertz distribution is one example of a widely-used distribution, with many applications to survival analysis. In this paper, several properties of the Gompertz distribution are studied.

A new generalization of the Marshall–Olkin Gompertz distribution

International Journal of System Assurance Engineering and Management, 2017
In this paper, a new distribution of the four-parameter lifetime model called the Marshall–Olkin Gompertz is proposed on the basis of the Gompertz distribution. It is a generalization of the Marshall–Olkin Gompertz distribution having constant failure rate and can also be constant, decreasing, increasing unimodal and bathtub-shaped depending on its ...

Stochastic dominance results under multivariate chain majorization for extreme order statistics of a generalized Gompertz distribution

Probability in the engineering and informational sciences (Print)
The generalized Gompertz distribution—an extension of the standard Gompertz distribution as well as the exponential distribution and the generalized exponential distribution—offers more flexibility in modeling survival or failure times as it introduces
