WebbReceiver operating characteristic (ROC) analysis is a graphical approach for analyzing the performance of a classifier. It uses a pair of statistics – true positive rate and false positive rate – to characterize a classifier’s performance. Webb縱軸為「正確接受率」: 正確地篩檢出高風險個案的人數占所有高風險個案人數的比率。 例如100個人當中,有40個人是高風險個案,而用新量表某個切截點分數可篩檢出30個人是高風險個案,其正確接受率為30/40 = 0.75。 為敏銳度:「VP÷ (VP+FN)」 命中率 正確接受和正確拒絕的個案人數佔整體篩檢人數的比率。 計算公式為:「 (VP+VN)÷ … main bodies of water
