Subject:      Cubic Clustering Criterion (CCC)

Hello SAS-friends,

The procedures PROC CLUSTER and PROC FASTCLUS use both a statistic called
Cubic Clustering Criterion (CCC). For each number of clusters the statistic
is computed, and a maximum value of that statistic indicates the optimal
number of clusters in a cluster algorithm. SAS computes it automatically.
I also made my own cluster algorithm, and I also want to compute the CCC.
Does somebody know a method or macro to compute this statistic for my own
cluster algorithm?
