Resumen de Estimation of the noncentrality matrix of a noncentral Wishart distribution with unit scale matrix.: A matrix generalisation of Leung¿s domination result
- català
El principal prop`osit ¿es estimar la matriu de no-centralitat de la distribuci¿o no-central de Wishart. Utilitzem el m`etode de Leng per`o generalitzat a una funci¿o matricial de p`erdua. Paral·lelament la identitat escalar de Leng per a una Wishart no-central ¿es generalitzada a una identitat matricial. Fem servir el concepte d'ordre parcial de L¿owner per a matrius sim`etriques

The main aim is to estimate the noncentrality matrix of a noncentral Wishart distribution. The method used is Leung's but generalized to a matrix loss function. Parallelly Leung's scalar noncentral Wishart identity is generalized to become a matrix identity. The concept of L¿owner partial ordering of symmetric matrices is used.
