delong_roc_ci(ground_truth: ndarray, predictions: ndarray, alpha: float = 0.95) → Tuple[float, ndarray][source]

Compute the ROC AUC and its DeLong confidence interval.

Parameters:

ground_truth – Binary labels (0/1), both classes present.
predictions – Probability-of-class-1 scores aligned to the labels.
alpha – Confidence level, e.g. 0.95.

Returns:

Tuple (auc, ci) where ci is the (lower, upper) bound, clipped at 1.0.
