Figure 1:

Sparse CCA was performed using CGH data on a single chromosome and all gene expression measurements. For chromosomes 6 and 9, the gene expression and CGH canonical variables, stratified by cancer subtype, are shown. It is clear that the values of the canonical variables differ by subtype. Pvalues reported are replicated from Table 1; they reflect the extent to which the canonical variables predict cancer subtype in a multinomial logistic regression model.
