I am trying to do cluster analysis on my data.
The approach was to do Factor Analysis on 15 continuous variables.
Then, run k-Means Cluster Analysis with the factor variables as inputs.
I chose to save the final cluster centers as a .sav file
Now, I will continue to get new data each month and I need to assign clusters to the new data based upon the 6 clusters that emerged from the initial dataset.
I opened the data file with new cases to try to classify them into clusters.
I checked "Read initial clusters" and chose the saved file with the cluster centers.
I then checked "Classify only" instead of "Iterate and classify". I checked to save cluster memberships.
When I run it, I get this error message:
The file referenced on the FILE subcommand does not contain initial cluster centers for at least one of the variables being analyzed.
Execution of this command stops.
Where did I go wrong in the process? I have attached the saved file of cluster centers.
