摘要
本文给出了 χ2 变量、T变量、F变量的W特征函数 ,并且由变量的独立性和矩的计算公式 ,分别得到独立的 χ2 变量、T变量。
This paper gives the walsh characteristic function of χ 2 variable, T variable and F variable,and obtains respectively the walsh characteristic function and moment of dyadic addition of cross independent χ 2 variable, T variable and F variable on the basis of the independent feature of variable and the moment computational formula.
