Figure 2From: A general strategy to determine the congruence between a hierarchical and a non-hierarchical classificationMethod to obtain the expected distributions for p. Simulations are performed by randomly permuting class labels while keeping the tree topology constant and cumulative hypergeometric values are ranked to obtain rank-specific random distributions of the p value. Although it is not indicated in the figure, results for each rank are obtained from independent sets of simulations.Back to article page
