摘要
利用行列向量的线性相关性证明二维离散型随机变量的独立性.结合两变量的边缘分布律所组成的矩阵的秩,并辅以相关的实例,拓展了独立性的证明方法.
This paper uses linear correlation matrix to prove the independence of the two-dimensional discrete random variables. Combined with the edge of the two variables distribution law of matrix rank, supplemented by relevant examples, the paper expands the proof method of independence.
