应用正态向量及独立随机向量的有关性质直接给出了方差分析中单项效应的抽样分布。但传统的证明方法(利用柯赫伦定理(Cochran))只给出了间接的证明,而这也正是“方差分析”中特别需要解决的问题。

Applying the nature about normal vector and independent random vector, the sampling distribution of single effect in variance analysis can be directly gotten. While traditional way of proof (according to Cochran) gives indirect proof. This is a question that must be solved in variance analysis.
