摘要
给出了构造不相关且不独立二维离散型随机向量的原理,并且提供了相应的方法.使用它们可以使教师在讲述不相关与独立概念时举证既方便又丰富.本文提供的参考程序可以使构造过程自动化.
This paper gives principle of constructing uncorrelated and depend bivariate discrete random vector and provides relevant methods, which can let teachers feel convenent and abundant while they look for demonstrations for teaching the concepts of uncorrelation and indenpendence. The reference program provided by this paper can make the constructive process automatized.
