The Cg criterion function (e4) , which illustrates data partitions by using the within-group total sum-of-squares (TSS) of Ward’s method. The feasible number of partitions is represented by a maximum of Cg. Values in brackets are the smallest similarity cut-points required to produce the indicated number of partitions. It is not unreasonable to expect superimposition of partitions; therefore, local maxima should indicate subtyping.
