During the computation we analyzed 10000 pairs of trees that were chosen at random from among all possible rooted binary trees with a particular number of leaves (n) under two the most popular models: the uniform model and the Yule model. In the case of the uniform model, an edge is added uniformly and randomly to any edge of the base tree. In this model, all phylogenetic trees have the same probability to be drawn. In the case of the Yule model, an edge is added uniformly and randomly to a pendant edge only, and the corresponding label is uniformly and randomly drawn as well. The following files contain the results:
