摘要
应用特征函数将一般非中心多元Wishart分布Wn(m ,V ,Δ)推广为广义的非中心多元Wishart分布Wn( β ,V ,Δ) ,β >0为实数 ,V≥ 0为非负定阵 ,Δ为对称阵 ,得到相应的广义多元Wishart分布的若干性质 .
The general non-central multivariate Wishart distribution W n(m,V,Δ)is generalized to the non-central multivariate Wishart distribution W n(m,V,Δ),where β>0 is a real number,V≥0 is a non-negative definite matrix and Δ is a symmetric matrix.We get some properties of the corresponding generalized multivariate Wishart distribution.
