Observed / raw is an exact relief numerator divided by a displayed decision denominator. A panel disposition appears once in each participating judge’s row; it is still one likelihood row.

Modeled is a posterior mean with a 95% interval after V3 adjustment. The comparison score places the focal judge with two average circuit peers; the likelihood itself uses every decision’s actual participating panel.

Observed publication mix recombines only the modeled Routine and Doctrine rates—using that judge’s observed track proportions. It does not reproduce the judge’s observed posture, offense, issue, or year mix.

Research summary

What stands out

Primary V3 remains the headline model. The summaries below update with the selected outcome and Routine/Doctrine weighting.

Judge comparison

Publication track is the dominant measured split: Doctrine relief is 19.8% versus 3.4% for Routine decisions.

Case mix

Issues and offenses describe case content. Publication mix is the separate Routine/Doctrine weighting used for modeled overall rates.

Robustness

Calendar year produces the largest typical movement; Senior-status share produces the largest single-judge movement.

Across every completed check, the median judge spans 0.36 percentage points; the widest span is 1.06 points. A narrow distribution means the estimate changes little under that tested assumption.

Method in one line: one disposition enters once; actual-panel weights sum to one; four chains contribute 8,000 retained posterior draws.
