摘要
二维随机变量独立性的判别法一般文献中都有,但方法不很简便。本文给出了一个简单的判断方法并证明其存在的合理性,而且推广至n维随机变量独立性的判别方法。
Judgmental methods on independence Of 2 dimensional random variable are common among papers,but all are complicated.This paper is able to provide a simple method and prove its justification of existence,and extends above conclusion to judge the independence on n-dimensional variables and its function.
