关于Kotz-Wishart分布:多元Varma变换
On a Kotz-Wishart distribution: Multivariate Varma transform
摘要:
我们引入了一个广义Wishart分布,即Kotz-Wishart分布。基于正态性假设的几个已有结果得到了推广。受Kotz-Wishart矩阵的pdf的特殊形式的启发,我们扩展了拉普拉斯变换算子。将这种广义拉普拉斯变换应用于矩阵辐角函数。
英文摘要:
We introduced a generalized Wishart distribution, namely, the Kotz-Wishart distribution. Several existing results based on the normality assumption have been extended. Inspired by the particular form of the pdf of the Kotz-Wishart matrix, we extended the Laplace transform operator. This generalized Laplace transform is applied to some functions of matrix argument.
