Use k-means test results for training set SPSS

[kalyanbl]

Hi,
I am working with  SPSS <https://mindmajix.com/spss-training>   (statistics)
for the first time. I used 1,000 rows of test data to run k-means cluster
tool and obtained the results. I now want to take those results and run
against a test set (another 1,000) to see how my model did.

I am not sure how to do this; any help is greatly appreciated!

Thanks

When you run the first clustering, specify that the cluster centers are written to a new dataset ("Write final").  Then switch to your test dataset and run K-means again, but change the Method setting to "classify only" and set "Read initial" to the dataset from the first round.  The cluster centers after the second round will be recalculated for the test dataset, so you might want to save them in another dataset for comparison
