Elo by weight class Reads and uses FighterAPI's Elo fighter ratings by weight class: leaderboards of active fighters, rating gaps as win probabilities, peak vs current, rating change per fight, and strength of schedule. Event lookup Lists UFC, PFL and Bellator cards and breaks down one card fight by fight.

Fight lookup Finds one UFC, PFL or Bellator fight and reports the result, method, round, time, scorecards and stat sheet.

Probability calibration Checks and fixes the calibration of fight win probabilities from a model or a rating: reliability tables, Brier score, log loss, calibration slope and intercept, Platt scaling and isotonic regression, and how to compare with the devigged closing line.
