Figure 7.

Split scores associated to a single edge in the tree from Figure 1 computed from 500 bp sequences simulated according to the Jukes–Cantor model. The base tree in Figure 1 has all branch lengths equal to . The single edge is the one that induces the split that bipartitions the taxa into groups of size and , . In each panel, scores for edge in the three trees are shown; these trees are topologically identical but certain branch lengths have been modified in each tree: (a) All branch lengths in the trees are equal, though of differing magnitude, changing the tree diameter; (b) all branch lengths EXCEPT that corresponding to edge are scaled; (c) ONLY the branch length that corresponds to edge is scaled; and d) all branch lengths in the clade corresponding to taxa are scaled. In each subfigure, boxplots show distributions of scores for 100 simulated data sets.
