Charged-Particle Multiplicity Moments as Described by Shifted Gompertz Distribution in e+e−, pp¯, and pp Collisions at High Energies

open access: yesAdvances in High Energy Physics, 2020
In continuation of our earlier work, in which we analysed the charged particle multiplicities in leptonic and hadronic interactions at different center-of-mass energies in full phase space as well as in restricted phase space using the shifted Gompertz ...

Marshal Olkin Marshal Olkin gompertz distribution [PDF]

open access: yesAIP Conference Proceedings, 2021
The aim of this paper is to propose a new flexible compound distribution named Marshal Olkin Marshal Olkin Gompertz (MOMOGo) distribution. Reliability characteristics besides several statistical properties of the proposed distribution have discussed. The maximum likelihood method, under a complete sample, is used to estimate the distribution parameters.

Unit-Gompertz Distribution with Applications

open access: yesStatistica, 2019
The transformed family of distributions are sometimes very useful to explore additional properties of the phenomenons which non-transformed (baseline) family of distributions cannot.

The McDonald Gompertz distribution: Properties and applications [PDF]

open access: yesCommunications in Statistics - Simulation and Computation, 2015
This paper introduces a five-parameter lifetime model with increasing, decreasing, upside -down bathtub and bathtub shaped failure rate called as the McDonald Gompertz (McG) distribution. This new distribution extend the Gompertz, generalized Gompertz, generalized exponential, beta Gompertz and Kumaraswamy Gompertz distributions, among several other ...

Bias of Maximum-Likelihood estimates in logistic and Cox regression models: A comparative simulation study [PDF]

open access: yes, 2003
Parameter estimates of logistic and Cox regression models are biased for finite samples. In a simulation study we investigated for both models the behaviour of the bias in relation to sample size and further parameters.

Determinants of the population growth of the West Nile virus mosquito vector Culex pipiens in a repeatedly affected area in Italy [PDF]

open access: yes, 2014
Background The recent spread of West Nile Virus in temperate countries has raised concern. Predicting the likelihood of transmission is crucial to ascertain the threat to Public and Veterinary Health.

Generalized Gamma – Generalized Gompertz Distribution

open access: yesJournal of Physics: Conference Series, 2020
AbstractIn this paper, we present a generated class of continuous distributions named H-G distributions. A new family of this class named generalized gamma - G along with one of its special cases, generalized gamma - generalized Gompertz distribution, are discussed. The cumulative distribution, probability density, reliability and hazard rate functions

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

open access: yesAxioms, 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.
