Solved – Assigning class to the cases after K means cluster analysis (SPSS)

k-meansspss

I have carried out PCA and then clustered the 6 resultant components using K-means clustering technique using SPSS. Normally SPSS adds a class variable for each case indicating its assigned group.

Is there any other method I can "calculate" the class variable (i.e. using component scores and REGR factor scores for the K means analysis given in the "Final Cluster centers" table????

Rerun your clusterization to save the final cluster centers as .SAV data file (check "Write final"). Then you open the data file with new objects to classify (this dataset may contain only new objects or a mix of new and old objects - it will make no difference). Check "Read initial" and choose here that saved file with cluster centers. Check "Classify only" instead of "Iterate and classify". Order to save cluster memberships under "Save" button. Run.
