Rank Graduation Accuracy

RGA measures how well model scores rank observations with respect to the target.

Main functions

`safeai.rga.rga_score`(y_true, y_score, *[, ...])	Compute Rank Graduation Accuracy.
`safeai.rga.rga_curve`(y_true, y_score, *[, ...])	Compute an RGA curve and normalized AURGA.
`safeai.rga.aurga_score`(y_true, y_score, *[, ...])	Compute only the area under the RGA curve.
`safeai.rga.compare_rga`(models, y_true, *[, ...])	Compare multiple models or probability arrays using RGA curves.
`safeai.rga.plot_rga`(result, *[, model_name, ...])	Plot one RGA curve or several RGA curves.
