+specificity, precision (or positive predictive value), negative predictive
+value, misclassification rate, accuracy, F-score---these are popular metrics
+for assessing performance of binary classifiers for certain thresholds.  These
+metrics are calculated at certain threshold values.  @dfn{Receiver operating
+characteristic} (ROC) curve is a common tool for assessing overall diagnostic
+ability of the binary classifier.  Unlike depending on a certain threshold,
+area under ROC curve (also known as AUC), is a summary statistic about how
+well a binary classifier performs overall for the classification task.  The
+ROCit package provides flexibility to easily evaluate threshold-bound
+metrics.")
