进行聚类分析的时候，你可以点击save选项卡，勾选要保存的变量

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
