如何用SPSS软件对聚类后结果进行判别分析

首先核实聚类分析结果的分类，是否与专业知识相符
然后对给定的这几个分类进行判别分析，在discriminate菜单中做

打开SPSS：Analysis→Classify →Discriminant:
Variables: ndependent (slen,swid,plen,pwid) Grouping(spno) Define range(min-1,max-3)
Classify: prior probability(All group equal) use covariance matrix (Within-groups) Plots (Combined-groups, Separate-groups,Territorial map) Display (Summary table)
Statistics: Descriptive (Means) Function Coefficients (Fisher’s,
Unstandardized) Matrix (Within-groups correlation, Within-groups
covariance, Separate-groups covariance, Total covariance)——输出结果，注意判别函数输出的表Canonical Discriminant Function Coefficients 以及分类结果表 Classification Result
