I used TwoStep clustering in order to cluster my binary data in SPSS. Now there is mentioned on IBM site, that:
"Note that the cluster features tree and the final solution may depend on the order of cases. To minimize order effects, randomly order the cases. You may want to obtain several different solutions with cases sorted in different random orders to verify the stability of a given solution. In situations where this is difficult due to extremely large file sizes, multiple runs with a sample of cases sorted in different random orders might be substituted." Link to the statement
I want to conduct a stability analysis now for the found clusters. Do someone know how to conduct a stability analysis for clusters (two step clustering used) in SPSS? For instance like the method from Blashfield Macintyre (1980)?
