三变量独立性的两个结论

Two Results about Independence of Three Random Variables

本文给出了三随机变量相互独立与条件独立的两个结论．其中结论２表明，三变量如果两两条件独立，则三变量一定相互独立．

In this paper, two results about independence of three random variables are given. The second result is: if any two variables of three are conditional independent, then the three variables are independent.
