Figure 1. nsNMF DNA methylation Clustering Based on 271 OCCC Tumors.

Figure 1.

(A) The estimated cophenetic correlation coefficient is plotted against the number of clusters (Rank), for k=2 through k=7, along with the corresponding 95% confidence interval that is empiricially calculated from 2,000 bootstrap samples. (B) For k=2 through k=7, the plot of the consensus matrix displays the agreement in cluster group across 100 clustering runs (red indicates 1=agreement, blue indicates 0=disagreement).
