Simulations on Hasegawa’s Tree. (a) Reconstruction accuracy of four different SR functions on different scaled versions of Hasegawa’s tree. The tree with scaled edge weights is depicted (left) next to the graph (right) plotting reconstruction accuracy of four SR functions. Different scales of the tree are considered, indicated by the diameter of the tree (X axis). Reconstruction accuracy (Y axis) is measured for each scaled tree by the average normalized RF distance between the reconstructed tree and the true tree across 10,000 simulated data sets. Simulations were carried out assuming a ti=tv ratio of R = 2 and sequence length of 500 bp. (b) A similar plot is shown for a semi-symmetric caterpillar tree.
