Figure 3. Disease prediction using a support vector machine model.

Shown are the mean (orange) and maximum (blue) areas under the curve (AUC) achieved in the validation set as obtained for each disease in the ten-fold cross-validation analysis. The mean and maxima refer to the best AUC's when testing a range of P-value thresholds from which to pick SNPs in training the linear SVM. SPA, spondyloarthropathy.
