当双线性形式的矩阵是矩形时,考虑正态变量中的双线性形式。给出了双线性和二次型累积量、联合累积量和联合累积量的显式表达式。建立了两个双线性形式以及一个双线性形式和一个二次型独立的充要条件。特例与已知结果吻合较好。
Bilinear forms in normal variables when the matrices of the forms are rectangular are considered. Explicit expressions for the cumulants, joint cumulants and joint cumulants of bilinear and quadratic forms are given. Necessary and sufficient conditions are established for the independence of two bilinear forms as well as a bilinear and a quadratic form. Special cases are shown to agree with known results.
