A new Gompertz-type diffusion process with application to random growth.

TL;DR: A new Gompertz-type diffusion process is introduced, by means of which bounded sigmoidal growth patterns can be modeled by time-continuous variables, with the main innovation that the bound can depend on the initial value.
Journal ArticleDOI

On Wishart distribution: Some extensions

TL;DR: In this paper, a unified approach that enables the Wishart distribution to be studied simultaneously in real, complex, quaternion and octonion cases under elliptical models was proposed.
Journal ArticleDOI

Distribution of the generalised inverse of a random matrix and its applications

TL;DR: In this paper, the Jacobian of the transformation Y = X +, where X + is the Moore-Penrose inverse of X, both in the general case and when X is a non-negative definite matrix, was found.

On Wishart distribution

TL;DR: In this article, a unified approach that enables the Wishart distribution to be studied simultaneously in real, complex, quaternion and octonion cases is proposed, where the joint density of the eigenvalues and the distribution of the maximum eigenvalue are obtained for real normed division algebras.
Journal ArticleDOI

The distribution of the residual from a general elliptical multivariate linear model

TL;DR: In this article, the distributions of internally and externally studentised residuals, assuming normal and elliptical distributions, were found for a general multivariate linear model of full or less than full rank.
