A Bivariate Generalization of Gamma Distribution [PDF]

open access: yesCommunications in Statistics - Theory and Methods, 2013
In this article, a bivariate generalisation of the gamma distribution is proposed by using an unsymmetrical bivariate characteristic function; an extension to the non central case also receives attention. The probability density functions of the product and ratio of the correlated components of this distribution are also derived.

Selecting the best distribution for modeling trends in low, medium, and extreme daily precipitation under climate change [PDF]

open access: yesAdvances in Statistical Climatology, Meteorology and Oceanography
Changes in mean precipitation and the frequency and intensity of extreme precipitation represent one of the most consequential aspects of anthropogenic climate change. This study evaluates a set of statistical distributions for modeling trends across the

A Generalization of Generalized Gamma Distributions

open access: yesPakistan Journal of Statistics and Operation Research, 2018
For the first time, a new generalization of generalized gamma distribution called the modified generalized gamma distribution has been introduced to provide greater flexibility in modeling data from a practical viewpoint. The new distribution generalizes some recently introduced generalizations of the gamma distribution.

On Generalized Gamma Distribution and Its Application to Survival Data

open access: yesInternational Journal of Statistics and Probability, 2019
The generalized gamma distribution is a continuous probability distribution with three parameters. It is a generalization of the two-parameter gamma distribution.

The Extended Generalized Gamma Geometric Distribution [PDF]

open access: yes, 2017
We propose and study the so-called extended generalized gamma geometric distribution. The proposed distribution has five parameters and it can be accommodate increasing, decreasing, bathtub and unimodal shaped hazard functions. The new distribution has a

Simulation of generalized Gamma distribution with maximum likelihood estimation and expectation-maximization algorithm on right censored data type 1 [PDF]

open access: yesDecision Science Letters, 2021
The Generalized Gamma distribution is very suitable for modeling data with various forms of hazard (risk) functions, which makes the Generalized Gamma distribution useful in survival analysis.

ON A NEW GENERALIZED BETA FUNCTION DEFINED BY THE GENERALIZED WRIGHT FUNCTION AND ITS APPLICATIONS

open access: yesMalaysian Journal of Computing, 2021
Various extensions of classical gamma, beta, Gauss hypergeometric and confluent hypergeometric functions have been proposed recently by many researchers. In this paper, further generalized extended beta function with some of its properties like summation

The gamma-uniform distribution and its applications [PDF]

open access: yes, 2012
summary:Up to present for modelling and analyzing of random phenomenons, some statistical distributions are proposed. This paper considers a new general class of distributions, generated from the logit of the gamma random variable. A special case of this
