摘要
多元线性回归分析中,自变量之间是相互独立的。在教育与心理领域中,往往不能满足此要求,而出现多重共线性问题。本文主要阐述了多重共线性的涵义、危害、诊断和处理,最后结合实例分析说明如何运用偏最小二乘回归法解决教育和心理统计中的多重共线性问题。
In the multiple linear regression analysis,variables are independent.In educational and psychological fields,often do not meet this requirement,and appears multicollinearity.This article mainly elaborates the meaning,harm,diagnosis and treatment of the multicollinearity,finally combines with examples to explain how to use the partial least squares regression to solve the multicollinearity problem in educational and psychological statistics.
