Generalised matricvariate -distribution
Jose A. Diaz-Garcia, Ramon Gutierrez-Sanchez
Assuming Kotz-Riesz type I and II distributions and their corresponding independent Riesz distributions the associated generalised matricvariate T distributions, termed matricvaria…
Moments of the Riesz distribution
Jose A. Diaz-Garcia
This article derives the first two moments of the two versions of the Riesz distribution in the terms of their characteristic functions.
Distributions on symmetric cones I: Riesz distribution
Jose A. Diaz-Garcia
The Riesz distribution for real normed division algebras is derived in this work. Then two versions of these distributions are proposed and some of their properties are studied.
Matrix Kummer-Pearson VII Relation and its Application in Affine Shape
Francisco J. Caro-Lopera, Jose A. Diaz-Garcia
A case of the matrix Kummer relation of Herz (1955) based on the Pearson VII type matrix model is derived in this paper. As a consequence, the polynomial Pearson VII configuration…
A modified Prékopa's approach in optimum allocation in multivariate stratified random sampling
Jose A. Diaz-Garcia, Rogelio Raos-Quiroga
A modified Prekopa's approach is considered for the problem of optimum allocation in multivariate stratified random sampling. An example is solved by applying the proposed methodol…
Multiple response optimisation: Multiobjective stochastic programming methods
Jose A. Diaz-Garcia, Mahdi Bashiri
The multiresponse surface problem is modelled as one of multiobjective stochastic optimisation, and diverse solutions are proposed. Several crucial differences are highlighted betw…
