AI Summary grounded in real data · zero hallucination
The model projects a Chicago Cubs victory with a 53% probability, though the edge against the market remains uncalculated. The primary driver supporting the Cubs is their advantage in '팀 평균자책(ERA)', while the main swing risks stem from deficits in '피타고리안 기대승률' and '팀 장타율(SLG)'. We transparently acknowledge that our model does not beat the market in the long run, warranting a cautious betting approach.
Logistic-regression statistical model — predicts Chicago Cubs vs Miami Marlins by accumulating the log-odds contributions of 12 proven structured metrics. Only structured metrics enter the probability; qualitative and folklore factors get a label only. Predictions are sealed with SHA-256 before the game.
