Model Card
Margin model of the form margin_ij = eta_i - eta_j + beta_home. It is the linear paired-comparison baseline for scoring margin targets.
Validation on this page uses stored season-level full-fit rows plus strict weekly rolling holdouts. Rolling ranks are based on average weekly log loss in the selected league/season. Current scope: All Games. All scored games in the selected league and season. AP Poll is excluded here.
Selected League / Season
Use the selected scope to inspect this model against peers and across rolling weekly holdouts.
| Full Fit AUC | 0.923 (#2) · 1469 games |
|---|---|
| 7-Day Holdout Log Loss | - · 0 games |
| Rolling Avg Log Loss | - · 0 windows |
| Window Wins | 0 |
Full-fit AUC is only available where the older stored-rating batch produced that model for the selected scope. Recency and ensemble families can still have valid 7-day and rolling holdout results even when the full-fit columns are blank.
Selected Scope Peer Table
Comparison snapshot for NCAAMD3 2025-2026. Rows are ordered by rolling log-loss rank; full-fit AUC may be blank for models that do not have legacy full-season rows stored for this scope.
