I have a question regarding what happens after I apply k-means clustering centers to a new data set.
Basically, I ran k-means clustering on a dataset1, saved the cluster centers, and applied it to a new dataset2 (set SPSS to "read initial" cluster centers and set the methodology to "classify only"). SPSS then outputs the clusters for my new dataset2. In the output however, there is also a set of initial and final cluster centers.
The initial cluster centers are the same ones that I've loaded in, but what is the final cluster centers shown here and why do they differ from the initial cluster centers that I loaded? Is my data still being classified using the cluster centers that I've loaded?
