Figure 4.

Difference in deviance from the ridge model. The boxplots give the difference in deviance between the six methods and ridge regression when using the combined data in a clinico-genomic model. The plots thus give a pairwise comparison between ridge regression and the other methods, in addition to giving an illustration of the variation due to regression methods corrected for the variation due to the 50 random training/test splits. For method abbreviations, see Figure 1.
