摘要
利用因子分析方法研究六种化学元素(即六个变量)之间的相关性,得到因子得分,将因子得分作为新变量,用聚类分析方法对六块火山岩标本分类,进而对六种区域火山岩的元素含量情况作出较好的判断.
In this paper,the factor analysis is applied to study the correlationship between six elements and obtain the factor scores.Taking the factor scores as new variables,cluster analysis is applied to classify six samples.The results determine the classification of the diffirent lava.
