Nigeria — 81% peak risk
Calibrated via isotonic refit on 810 live outcomes (2026-05-20). See calibration drift → · Nigeria country profile →
The Voidly Sentinel model forecasts a peak shutdown probability of 80.9% for Nigeria over the next 7 days, with the highest risk on day 7 (Thu, May 28). Average risk across the window: 78%.
90% conformal interval: [46%, 100%] — empirical coverage 90.4% (target 90%).
Per-day risk
Dashed line: 50% threshold. Bars colored by risk band.

Honest caveats
- The model's base AUC on a time-based holdout is
0.50(random on novel events). LOCO median AUC is0.91. The calibrated number you see above is the most-honest operational figure but it's NOT a guarantee. - Calibration was refit on 2026-05-20 on 810 live outcomes — it's good for the 30 watched censoring countries but will drift if the world changes. Nightly recalibration runs at 04:30 UTC.
- A 70% forecast doesn't mean a shutdown is guaranteed; a 20% forecast doesn't mean it's safe. The 90% conformal interval is the honest uncertainty band.
