I understand the idea od the CCC is to compare the R^{2} you get for a given set of clusters with the R^{2} you would get by clustering a unfoirmly distributed set of points in a* p* dimensional space. However what if I get negative values in the CCC plot but the peaks in the CCC plot still indicate a number of clusters that explains a good deal of variation (as evidenced by the corresponding R^{2 }value with that number of clusters in the Cluster History table)? Please advise. Thanks!

Small correction: The CCC statistic is based on research by Warren Sarle, not Warren Kuhfeld.

I always confuse those two myself.
