  1. The table summarizes the performance of the different P values for the threshold inclusion rule. The numbers of multi-member clusters and singletons are given separately, so that the total numbers of clusters at each P value are 36, 14, 11, 10, 10, and 10, respectively. The Silhouette width and the average of the standard deviations of the distributions of intra-cluster similarities in each cluster are also shown.
