Visualization of Lasso shrinkage in the Hu subtypes. Table indicating the order in which the weights in w become non-zero, when changing λ. The figure shows the results for the human samples split over the five subgroups defined by Hu et al. . Gene sets that correspond to these four Hanahan hallmarks were chosen as components. The linewidth is proportional to the total number of samples in that clinical subgroup. Apopt: Apoptosis; Growth: Growth; Angio: Angiogenesis; Repli: DNA Replication.
