Table 6 Definitions of performance measures for PCA control readjustment prediction

From: Decision tree-based learning to predict patient controlled analgesia consumption and readjustment

Performance Measure Definition
TPRa (True Positive Rate) TP/(TP+FN)
FPR (False Positive Rate) FP/(FP+TN)
Precisionb TP/(TP+FP)
F-score 2*TPR*Precision/(TPR+Precision)
  1. aTrue Positive Rate is also known as Sensitivity or Recall.
  2. bPrecision is also known as Positive Predictive Value.
