Table 1.

Performance comparison on synthetic data. Training and testing correlation coefficients (mean±std) of 5-fold cross-validation are shown for NS-SCCA, AGN-SCCA and GGL-SCCA. The best value are shown in boldface. The AUC (area under the curve) values (mean±std) of canonical loadings are also shown.
