Modified TWINSPAN classification in which the hierarchy respects cluster heterogeneity

Original language description

Aim To propose a modification of the TWINSPAN algorithm that enables production of divisive classifications that better respect the structure of the data. Methods The proposed modification combines the classical TWINSPAN algorithm with analysis of heterogeneity of the clusters prior to each division. Four different heterogeneity measures are involved: Whittaker's beta, total inertia, average S circle divide rensen dissimilarity and average Jaccard dissimilarity. Their performance was evaluated using empirical vegetation datasets with different numbers of plots and different levels of heterogeneity. Results While the classical TWINSPAN algorithm divides each 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.
