The Weibull-Gamma Distribution: Properties and Applications [PDF]

Entropy, 2019
A new member of the Weibull-generated (Weibull-G) family of distributions—namely the Weibull-gamma distribution—is proposed. This four-parameter distribution can provide great flexibility in modeling different data distribution shapes.

A bimatrix variate gamma distribution

Results in Applied Mathematics, 2022
In this article, a bimatrix gamma distributions is introduced. Various mathematical properties of the proposed distribution like marginal distributions, expected values, entropies, and moment generating function are derived.

The variance-gamma ratio distribution

Comptes Rendus. Mathématique, 2023
Let $X$ and $Y$ be independent variance-gamma random variables with zero location parameter; then the exact probability density function of the ratio $X/Y$ is derived.

A Simulation-Based Testing of Difference in the Means of Gamma-Distributed Positive Quantities

Applied Sciences, 2023
This paper presents a simulation-based testing procedure that can be easily applied by practitioners who try to determine whether two gamma-distributed variables have the same expected values. From both theoretical and practical points of view, the gamma

Stability and Bifurcations in a Nutrient–Phytoplankton–Zooplankton Model with Delayed Nutrient Recycling with Gamma Distribution

Mathematics, 2023
Two nutrient–phytoplankton–zooplankton (NZP) models for a closed ecosystem that incorporates a delay in nutrient recycling, obtained using the gamma distribution function with one or two degrees of freedom, are analysed.

Modelling Spray Pressure Effects on Droplet Size Distribution from Agricultural Nozzles

Applied Sciences, 2021
For spray applications, drop size is the most important feature as it affects all aspects of a phytosanitary treatment: biological efficacy, environmental pollution, and operator safety.

Estimation of P{X < Y} for gamma exponential model [PDF]

Yugoslav Journal of Operations Research, 2014
In this paper, we estimate probability P{X < Y} when X and Y are two independent random variables from gamma and exponential distribution, respectively. We obtain maximum likelihood estimator and its asymptotic distribution.
