Interactive model leaderboard
Compare every pricing, payment, and actuarial model side-by-side on a shared metric surface — backtest MAPE, 90% CI coverage, auditability, and equity — then filter by scenario and region to see which model dominates under the constraints you actually face. The winner is chosen by a weighted composite you control below; the "why this model wins" panel spells out the deltas.

Worked case — regenerate every model & re-rank by dominance

Edit the costs, QALYs, comparator anchor, and WTP threshold below. Every pharma model recomputes its recommended price, ΔC, ICER, and net monetary benefit NMB = λ·ΔE − ΔC live. The ranking sorts by NMB (payer value); models with strong dominance (ΔC < 0 AND ΔE > 0) are flagged.

Cost-effective at λ
ICER color bands: green < λ/2 (highly cost-effective), sky < λ, amber < 1.5λ, rose ≥ 1.5λ. NMB uses your λ directly, so raising the WTP slider makes marginal models flip to cost-effective in real time.

Weight sensitivity — how stable is each rank?

Resamples the composite weights uniformly around the current settings (each weight perturbed by ±spread, clamped ≥ 0, then normalised) and re-runs the ranking 300 times. Low rank SD and a high share of top-1 finishes mean the model wins across a wide neighbourhood of weight choices, not just at your current slider positions.
