Explains the computation of the cubic clustering criterion (CCC). The CCC can be used to estimate the number of clusters, using Ward's minimum variance method, k-means, or other methods based on minimizing the within-cluster sum of squares. The report also explains how to use the Monte Carlo method to evaluate the performance of the CCC.
