ROC Curves, continued
To derive sensitivity/(1-specificity) pairs:
- For trees: each leaf is assigned a probability of having MI for a case that arrives there
- For LR: the equation already calculates the probability of having MI for each case
- Then, the threshold probability for considering a case to be called MI is varied:
- set at each leaf probability (for trees) or at values 0, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100% (for LR)
