【摘要】 给出了从随机向量的函数的独立性推出该向量本身独立性的两个结果。由此证明:若完备正交表L_N（m^K）的N个实验数据X=（x₁x₂…,x_N）′线性正态,则在诸x₁独立同分布于N（μ,σ²）的统计假设下,各列极差R₁,R₂,…,R_k相互独立。更多还原

【Abstract】 In this paper, two results of independence of the random vectors have been got from independence of the functions of random vectors and from the second result, the independence of ranges at all columns in orthogonal list have resulted under centain hypothesis.更多还原
