Lost Thunder
Hedonic fair-value coverage for 25 Special Illustration Rare and Illustration Rare cards from Lost Thunder. Prices below are spot snapshots from the live Hedonix database; sign in to app.hedonix.tech for the full dataset including model fair value and risk context.
Hedonix prices each card by its observable attributes — raw price, rarity, character tier, artist, market velocity, and PSA grading population — using a log-linear hedonic regression refit nightly across the full coverage universe.
The model explains 87.9% of cross-sectional price variation in-sample (n=360, R² 0.879) and holds 79% R² on completely unseen sets (leave-one-set-out cross-validation). See the working paper for the full specification.
