what is the roc of a rare event curve what's the correct cutoff for over sampling what is the average true positive roc when is an over sampled train set a true class distribution when you use a test set how many observations are false negatives what is a good over sample rate for a rare event what is over-sampled and over sampled what is the ROC of a test set if a curve is oversampled can I tell the ROC? what is the ROC and why is it important? what would be a roto curve for a rare event what is the cutoff for using over sampled what is the over sampled roo of a rare event what is the roc curve used for ROC for over sample model what is the rotor of a train set what is the rate of false positives in over sampling what is the roc curve for rare event what is the ROC for a rare event how to calculate a roc curve
