Cluster analysis units
I'm trying out the cluster anaysis tool after running Principle Component analysis, extracting the highest corellative variables, and standardizing their units ((x-mean)/stndard dev). I am then using Wards method with Squared Euclidean distances, and looking at the resulting dendrogram. I understand that the distances are somehow related to SSE values, but what specific units would be prescribed to the x axis? Keep in mind that the units are standardized prior to cluster analysis.
