ROC (1) 썸네일형 리스트형 [R] Assessment of the Performance of Classifier 1. Two types of Missclassification errors We can change the two error rates by changing the thershold from 0.5 to some other value in [0, 1]. \(\hat{Pr}(Default = Yes|Balance, Student) \ge \alpha\) \(\alpha\) is a threshold. If \(\alpha\) ↑, FN increase while FP decrease. If \(\alpha\) ↓, FN decrease while FP increase. 2. [Ex] Changes in errors along with Thresholds thresholds 이전 1 다음
