For rare violent re-offense, risk assessment tools face a structural Likelihood Ratio Wall limiting positive predictive value to low levels with current discrimination power, worsened by a Surveillance Ceiling from over-policing that reduces maximum precision for over-policed groups even at equal re
Model evaluation in supervised learning should be treated as a context-dependent, decision-oriented process aligned with operational objectives rather than relying on a small set of aggregate metrics.
