Central matricvariate and matrix multivariate T distributions
Jose A. Diaz-Garcia, Ramon Gutierrez-Jaimez
Several distributions are studied, simultaneously in the real, complex, quaternion and octonion cases. Specifically, these are the central, nonsingular matricvariate and matrix mul…
Matricvariate and matrix multivariate Pearson type II distributions
Jose A. Diaz-Garcia, Ramon Gutierrez-Jaimez
This paper proposes a unified approach to enable the study of diverse distributions in the real, complex, quaternion and octonion cases, simultaneously. In particular, the central,…
On Wishart distribution
Jose A. Diaz-Garcia, Ramon Gutierrez-Jaimez
This paper proposes a unified approach that enables the Wishart distribution to be studied simultaneously in the real, complex, quaternion and octonion cases. In particular, the no…
An identity of Jack polynomials
Jose A. Diaz-Garcia, Ramon Gutierrez-Jaimez
In this work it is propose an alterative proof of one of basic properties of the zonal polynomials. This identity is generalised for the Jack polynomials.
Noncentral bimatrix variate generalised beta distributions
Jose A. Diaz-Garcia, Ramon Gutierrez-Jaimez
In this paper, we determine the density functions of nonsymmetrised doubly noncentral matrix variate beta type I and II distributions. The nonsymetrised density functions of doubly…
Complex bimatrix variate generalised beta distributions
Jose A. Diaz-Garcia, Ramon Gutierrez-Jaimez
In this paper, the study of bivariate generalised beta type I and II distributions is extended to the complex matrix variate case, for which the corresponding density functions are…
