(a) The outer product of the sorted eigenvectors uand v of the 2nd eigenvalue of the equal row- and column-sum bistochastic-like matrix B applied to a dataset with three types of lymphoma: CLL (C), FL (F), and DLCL (D). Sorting of v orders the patients according to the different diseases. (b) As in (a), the 2nd singular value contribution to the biclustering method (C −1 A T R −1 A) of lymphoma CLL (C), FL (F), DLCL (D) partitioned the patients according to their disease, with one exception. We preselected all genes that had complete data along all experimental conditions (samples).
