| 摘 要： | 主成分分析法常被应用于综合评价与监控,其评价与监控值就是样品的主成分得分值,故尽快求出主成分得分值是实现综合评价与监控的重要环节之一。多数人使用的SPSS软件求解主成分得分值的方法较慢,甚至出现错误。而从理论上给出主成分得分值与未旋转因子得分值的关系式,并利用SPSS软件因子分析模块中未旋转因子得分值,一步算出主成分得分值,则大大简化了计算,其效果比以前的方法好。同时也改正了一些新版文献的错误。

| Abstract: | Principal component analysis often been used to conduct comprehensive evaluation and monitoring.The value for this purpose is the sample score of principal component.Hence to obtain it in a fast way becomes very important for the process of comprehensive evaluation and monitoring.The mostly used method for obtain the score of principal component works slowly and has mistakes.This article derived the functional expression between that score and the score before rotation.The author use the score before rotation to calculate the score of principal component in one step,simplifies the computation tremendously.Also corrects the mistakes in reference. |
