Fig. 6

Analysis results for the TCGA LUAD, KIRC, and pan-cancer data sets, using elastic net, I-Boost-CV, and I-Boost-Permutation on nested models. In the left panel, the leftmost dots are fixed at zero, and each remaining dot represents the average NRI obtained by fitting elastic net, I-Boost-CV, or I-Boost-Permutation over 30 training and testing data set pairs. Each dot except the leftmost dots represents the maximum NRI between a model that contains one more data type than the model corresponding to the dot on the left and the model corresponding to the dot on the left. Above each dot, the name of the additional data type is included. In the right panel, the average C-index values and the average numbers of selected variables for the models shown in the left panel are plotted. The arrows indicate the orders of models with respect to the number of data types they contain. See the caption of Fig. 1 for the abbreviations of the data types
