Actual and predicted clearance pathways of 10-fold cross-validation using the rectangular-based predictor
The shaded entries represent the numbers of drugs classified into a correct clearance pathway by the classification system.

↵a Dual: the number of drugs classified into two pathways.
↵b None: the number of drugs classified into none of the pathways.
↵c Recall: the proportion of drugs correctly classified into a pathway to that of the total number of drugs that are actually eliminated through that pathway.
↵d Precision: the proportion of drugs correctly classified into a pathway to that of the total number of drugs classified into that pathway.
↵e Overall precision: the ratio of the number of drugs correctly classified to that of those predicted to be in the same pathway.
↵f Accuracy: the proportion of drugs correctly classified to that of the total number of drugs in the training data set.
