Survival Function Estimation for Fuzzy Gompertz Distribution with neutrosophic data

International journal of neutrosophic science, 2023
A relatively recent area of research known as neutrosophic statistics deals with data that are ambiguous, indeterminate, and inconsistent. By embracing the idea of neutrosophy, which denotes the existence of three components in a statement: truth ...

Lower k-record values from unit-Gompertz distribution and associated inference

Journal of Statistical Computation and Simulation, 2023
Mazucheli et al. [Unit-Gompertz distribution with applications. Statistica. 2019;79(1):25–43.] introduced the unit-Gompertz (UG) distribution and studied some of its properties.

Statistical inference of Gompertz distribution under general progressive type II censored competing risks sample

Communications in statistics. Simulation and computation, 2022
Gompertz distribution is a significant and practical continuous lifetime distribution, which plays an important role in reliability engineering. A Gompertz distribution competing risks model is discussed and studied under general progressive censoring in

Fitting Real Data Sets by a New Version of Gompertz Distribution

Modern Journal of Statistics
The Poisson Inverted Shifted Gompertz distribution is a new type of distribution that comes from the Poisson-generating family of distributions and is based on the "inverted shifted Gompertz distribution." This distribution has significant statistical ...

Bayesian inference of Unit Gompertz distribution based on dual generalized order statistics

Communications in statistics. Simulation and computation, 2021
In this article, we consider the estimation problem of Unit Gompertz distribution with parameters α and β under the framework of dual generalized order statistics. This article is purely devoted to present the Bayesian view of estimation of Unit Gompertz

An Extension of the Gompertz Distribution for Modeling COVID-19 Mortality Dynamics

International Journal of Analysis and Applications
The Gompertz distribution is widely used in medical and reliability studies, particularly for modeling mortality rates and failure data. However, it has limitations in capturing complex data behaviors, such as heavy tails and varying hazard rate shapes ...

On a progressively censored competing risks data from Gompertz distribution

Communications in statistics. Simulation and computation, 2021
We study a competing risks model using Gompertz distribution under progressive Type-II censoring when probability distributions of failure causes are identically distributed with common scale and different shape parameters.

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.

Another extension of the Gompertz distribution : Properties, applications and regression

Journal of Statistics & Management Systems
Modelling heterogeneous data sets is an emerging research area that is growing steadily. This paper introduces the Harmonic Mixture Gompertz distribution, a new mixture model derived from the weighted harmonic mean of the survival functions of two ...

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.
