AUROC: Area Under Receiver Operating Characteristic Curve

Description

Compare area under the receiver operating characteristic curve (AUROC) for binary (e.g., logistic) models. The area under the ROC curve provides a measure of the model's classification accuracy averaged over all possible threshold values.

Usage

AUROC(object, ...)
# S3 method for spglm
AUROC(object, ...)
# S3 method for spgautor
AUROC(object, ...)

Value

The area under the receiver operating characteristic curve.

Arguments

object

A fitted model object from spglm() or spgautor()) where family = "binomial" and the response values are binary, representing a single success or failure for each datum.

...

Additional arguments to pROC::auc().
