Results of clustering using the weighted average distance criteria for gene family COG1230 from the Tree of Life data set using DTL costs 2, 3, 1, respectively with N=27. On the top are the pairwise distances for the entire MPR space. The second row shows the pairwise distances for k=2 clusters. The third row shows the pairwise distances for k=3 clusters obtained using the same method. In this case, the initial distribution is bimodal, suggesting the presence of multiple clusters. For k=2, the local improvement is 1.48 and both distance distributions are unimodal, indicating that two clusters were identified. For k=3, the local improvement is 1.10 and the distributions are remain unimodal, suggesting the presence of just two clusters
