摘要: 得到在多维随机变量中寻找主要因素(主要分量或主成分)的一种方法. 找出主要分量并证明其余分量均可表示为主成分的线性组合, 从而解决了多维随机变量的各个分量之间所存在的线性关系问题.

关键词: 主成分, 分量相关, 线性表示

Abstract: Suppose that X=(X1,X2,…,Xn)′ is a n dimension random vector, we have found the main components in vector X, the so called main components don't contain linear relation and the others components of X can be expressed as the linear combination of the main components.

Key words: main component, factor correlation, linear express
