关于复共线影响点诊断方法的研究

Research on Diagnosis Method for Multicollinear Influential Points

基于核主成分分析方法,提出了复共线影响点的核主成分诊断以及剔除准则.数值试验表明,利用核主成分分析方法诊断剔除复共线影响点比用主成分方法更有效.

A new kernel principal component diagnosis method for muhicollinear influential points with the e-liminate criterion is put forward based on kernel principal component analysis. Numerical examples shows that eliminate muhicollinear influential points according to kernel principal component diagnosis method is more ef-fective then that of principal component diagnosis method.
