Model Card

Neutral-context sum of Stocks For Elo and Stocks Prevention Elo.

Validation here is out of sample. From two weeks into each season, a model trained on earlier games predicts each following week without learning from that week. Predictions use the players' observed minutes; each point is the minutes-weighted predicted and actual rate in that player's games. The source inputs were not verified as identical to the published model revision.

Held-out player predictions

NCAAW 2025-2026: 3745 players with at least 100 held-out minutes. Across players, predicted and actual correlate at r = 0.95 (weighted by held-out minutes). Across these player averages, weighted R² = 0.79 (relative to the weighted mean of actual held-out outcomes). Per held-out team game, squared error is 24.4% below predicting the league average. Each dot is a player (500 with the most held-out minutes are plotted; larger dots had more); on the dashed line, actual equals predicted. Select a dot for the player.
