Description¶
ABROCA is a fairness metric proposed by Gardner et al. (2019) and adopted by several reviewed studies. "This metric measures the absolute value of the area between the baseline group ROC curve ROCb and the comparison group(s) ROCc. The lower the ABROCA value, the less unfair the algorithm." Unlike threshold-dependent metrics such as equalized odds, ABROCA evaluates model discrimination across all thresholds and can be computed directly from prediction modeling results with minimal computational requirement.
