WebThe maximum value of the Youden index is 1 (perfect test) and the minimum is 0 when the test has no diagnostic value. The minimum occurs when sensitivity = 1−specificity, i.e., represented by the equal line (the diagonal) in the ROC diagram. The vertical distance between the equal line and the ROC curve is the J -index for that particular cutoff. http://chenyuan.date/2024/06/Youden_index/
