Matrix‐variate beta distribution
International Journal of Mathematics and Mathematical Sciences, Volume 24, Issue 7, Page 449-459, 2000., 2000 We propose matrix‐variate beta type III distribution. Several properties of this distribution including Laplace transform, marginal distribution and its relationship with matrix‐variate beta type I and type II distributions are also studied.

On the noncentral distribution of the ratio of the extreme roots of wishart matrix
International Journal of Mathematics and Mathematical Sciences, Volume 4, Issue 1, Page 147-154, 1981., 1981 The distribution of the ratio of the extreme latent roots of the Wishart matrix is useful in testing the sphericity hypothesis for a multivariate normal population. Let X be a p × n matrix whose columns are distributed independently as multivariate normal with zero mean vector and covariance matrix ∑.

Generalization of Log‐Xgamma Distribution: Applications and R Shiny Web‐Tool
Journal of Mathematics, Volume 2025, Issue 1, 2025.The two‐parameter xgamma distribution is employed to create a novel distribution that is suitable for bounded datasets within the interval (0, 1). A comprehensive analysis of the statistical properties of this newly proposed distribution is conducted.

Journal of Mathematics, Volume 2024, Issue 1, 2024.This paper introduces a new probability distribution called the mixture symmetric gamma (MSG) distribution, which is defined as a mixture of two symmetric gamma distributions. Its statistical properties and applications are explored. We first examine its mathematical properties, including the possible shapes of the corresponding probability density ...
