ROC curve for a fitted model — sdt

Draws the receiver operating characteristic of an sdt_fit() model on its held-out split. With more than two classes, one curve per class is drawn one-versus-all, which is what roc_auc's Hand-Till estimator summarises.

Usage

sdt_roc(model)

Arguments

model: An sdt_model from sdt_fit().

Value

A ggplot2 object.

Examples

# See ?sdt_fit for a runnable example.

#>     yardstick::metric_set(yardstick::roc_auc, yardstick::accuracy, 
#>         yardstick::kap, yardstick::f_meas)
