- 0.18 · 19 events · 24-month window
- Skill1 minus the person's Brier divided by a reference Brier on the same clusters. Positive beats the reference; 0 equals it. Method › against base ratesThe probability a published external study gives an event of that class and stage, fixed at intake. Halved when the item window is shorter than the class median time to decision. Never learned from the ledger's own items. Method ›
- needs 10 paired events · 3 now
- Market skillThe last public prediction-market price up to 7 days before the statement, on a question whose deadline is within one quarter of the item's. Used for the market row and market skill. Method ›
- needs 5 events with a market quote · 0 now
- Leave-one-out changeThe largest change in the mean Brier when one cluster is removed. A stability check next to the interval. Method ›
- 0.03
- Affiliated shareA flag on an item where a third party decides the event but the person has a disclosed role, stake, employment, board seat or trial site in an entity named in the event. Scored and flagged; the headline is shown with and without. Method ›
- 3%
- Headline without affiliated itemsThe headline metrics recomputed on clusters with no affiliated item. Shown only when both sides have enough clusters. Method ›
- 0.20
- Murphy decompositionThe mean Brier split into reliability (how far the words were from the truth), resolution (how much the words sorted outcomes) and uncertainty (how hard the events were): B = REL - RES + UNC. Method ›
- needs 30 resolved events · 21 now
- Scoreable share
