随机变量与其和的相关度的判定

THE JUDGEMENT OF CORREL ATIVITY BETWEEN RANDOM VAIABLES AND THEIR SUM

本文首次给出关于随机变量与其和相关系数的几个结论,使我们能够仅根据随机变量本身的数字特征便可对它们与和的相关程度大小作出比较判断。

In this paper, the results are given for the relative factor of random variables and their sum, by it, we can judge the relative factor for random variables and their sum from the self—random variables onlv。
