LOOCV using the ROC based classifier
The function performs classification by leave-one-out-cross-validation (LOOCV) using the ROC based classifier: Features are combined to a metagene by the mean expression and samples are ranked according to the metagene expression. The metagene threshold that yields optimal accuracy in the training samples is then used to classify new samples according to their metagene expression values.
