    While the classical TWINSPAN algorithm divideseach cluster coming from the previous division step, the modified algorithm divides only the most heterogeneous cluster in each step. The four tested heterogeneity measures may produce identical or very similar results. However, average Jaccard and Sorensen dissimilarities may reach extreme values in clusters of small size and may produce classifications with a highly unbalanced cluster size.
