摘要: The distributions of non-central Quaternion Wishart matrix and its latent root s matrix are derived by using Zonal polynomials with quaternion matrix arguments and their properties.关键词: Quaternion quaternion zonal polynomials Noncentral Quaternion Wishart Distribution ...
1) wishart distribution Wishart分布1. In this paper, the authors generalize the definition of χ 2 distribution and introduce a quasi χ 2 distribution, and then prove several properties of it, find the necessary and sufficient conditions of independence about multivariate normal distributions, matrix...

Multivariate Anal. 94 (2005) 271–299] derived the asymptotic joint distribution of the eigenvalues and the ...
To utilize the relationship between the decision maker and experts, and to avoid problems associated with different scales and ranges of the variables, we assume that the decision maker transforms the experts' quantiles in terms of her own prior distribution for each Xi. A model using such a ...

is the number of degrees of freedom, and we want to keep it low if the prior is to be relatively noninformative. A matrix S has inverse Wishart distribution if its inverse has Wishart distribution . Again, since for large the inverse will look like , for large S will look like . More...
Percentage points of the joint distribution of the extreme roots of the random matrix S1(S1+S2)−1 Let S(1) and S(2) be independently distributed as central Wishart matrices with n(1) and n(2) degrees of freedom respectively. Also, let theta sub 1 and th... F.J. Schuurmann,V....
