Table 5 Confusion matrix of MAS and RMA clustering results. Clustering into k = 12 clusters was performed using k-means clustering, using correlation distance on 3000 probe sets. A cell at position (i, j) shows the number of samples assigned to cluster i on data pre-processed using MAS and to cluster j on data pre-processed using RMA. The Jaccard index between these two clusterings is 0.55.
