Research leads
Ranking uses a fixed-seed Isolation Forest over amount, issue breadth, agency breadth and lobbyist count. Scores describe unusual profiles in the observed cohort. They are not calibrated risk probabilities.
Association checks
Amount versus reported agency breadth within the same period and measure. Estimates use rank correlation, 499 permutations and a correction across tested cohorts. Shared firms and incomplete coverage limit interpretation.
