AucResult

@Serializable

@SerialName(value = "AucResult")

data class AucResult(val auc: Double, val totalPositives: Double, val totalNegatives: Double, val positives: DoubleArray, val negatives: DoubleArray, val lowerBound: Double, val upperBound: Double) : Result(source)

AUC snapshot with the per-bin counts needed for merge. auc is NaN until at least one positive and one negative have been observed; consult totalPositives / totalNegatives to detect that case.
