The performance is measured by leave-one-out cross validation. To get unbiased result, the variable selection and training are done in training arrays, which is completely independent with the testing array. (A) The comparison in classification performance of SVM-RFE selected variables using individual isoforms and the overall mRNAs. (B) The comparison in classification performance of variable subsets selected by SVM-RFE and t-test, using individual isoforms.
