第二类多元t分布模型中参数的一致最小风险同变估计的存在性

Existence of the Uniformly Minimum Risk Equivariant Estimation for the Second Types of Multivariate t Distribution Parameters

利用多元正态分布和gamma分布定义了另一种形式的多元t分布,称为第二类多元t分布,并研究了第二类多元t分布模型中参数的一致最小风险同变估计的存在性问题.

The multivariate normal distribution and gamma distribution are used to define another form of multivariate t distribution, defined as the second class of multivariate t distribution, and second classes of multivariate t distribution model parameters of the UMRE estimation problem are also probed.
