摘要
利用统计软件SPSS二次开发功能,结合C#开发出主成分回归模型的独立分析模块,为在该软件中消除变量共线性提供一条解决方案,为减少手工计算提出一种思路.为了方便交流和进一步的开发,发布分析模块以供下载.
The method of principal component regression is used to eliminate or diminish the effect of multiple co-linearity. The method of second time exploitation united with C # is suggested to exploit an independent analysis module of principal component regression, which can execute directly in SPSS instead of large numbers of hand computation. A correspondingly executable programme is supplied for download and further discussion.
