将准对角矩阵F 分布的定义推广到左球准对角矩阵分布中,给出了推广的准对角矩阵F 分布变量的矩量表达、特征根分布及其关于对角非奇异矩阵变换的不变性。
將準對角矩陣F 分佈的定義推廣到左毬準對角矩陣分佈中,給齣瞭推廣的準對角矩陣F 分佈變量的矩量錶達、特徵根分佈及其關于對角非奇異矩陣變換的不變性。

In this paper,we extend the definition of elliptically contoured quasi-diagonal matrix F to the left-spherically quasi-diagonal matrix distribution family,and obtain its moment and the distribution of characteristic roots,then we discuss the invariant of elliptically contoured quasi-diagonal matrix F defini-tion under diagonal nonsingular matrix transformations.
