- a Level: The number of features selected in each recursive step.
- dReduceTest: Relative reduction in the mean test error rates of SVM comparing to that of WV, calculated as: (average TestErrorWV - average TestErrorR-SVM)/(average TestErrorWV).
- e P(test-diff): The p-value of the observed differences in test error rates, by paired t-test.
- f ImproveRec: Relative improvement in the proportion of recovered informative genes by R-SVM comparing to that by WV, calculated as: (average #RECR-SVM - average #RECWV)/(average #RECWV), where #REC represents the number of recovered true informative genes with the method stated in the subscript.
- g P(rec-diff): The p-value of the observed difference in proportion of recovered informative genes, by paired t-test.
