Cophenetic correlation coefficient. Each point on the graph was obtained from 50 runs of the Brunet et al's algorithm [4]. This graph indicates the robustness of the clusters for different values of the factorization rank. There is a large decrease in the stability for r = 5, compared to lower ranks.
