sci.ROC-AUC-trapezoidal Calculator
Calculates ROC (Receiver Operating Characteristic) curve points and AUC using the trapezoidal rule from predicted probabilities and binary labels. AUC = 0.5 is random classification; AUC = 1.0 is perfect — AUC is threshold-independent and preferred over accuracy for imbalanced datasets.
