摘要
基于闭偏态正态分布,提出了闭偏态矩阵正态分布的定义,给出其性质,并在此基础上研究闭偏态矩阵正态分布二次型,从矩阵的角度探讨了偏态性质。
Based on the closed skew-normal distribution, the paper presents the definition and properties of the closed skew-normal matrix distribution, and investigates its quadratic forms. From the point of matrix, we creatively study its skew properties.
