WebIn short, positive predictive value (PPV) is the metric that users are most familiar with – it’s the most ‘real-world’ statistic. PPV is highly dependent on the prevalence of a pathology – as we saw in the table above, algorithms searching for low-prevalence conditions have significantly lower PPVs than higher prevalence conditions. Webalyzed the fairness of COMPAS in terms of predictive parity, and found that COMPAS outcomes systematically over-predict risk for women, thereby indicating systemic gender bias. However, the findings of the ProPublica study were rejected by Northpointe (COMPAS developer), claiming their algorithm is fair because it is well calibrated [20].
