AI Summary grounded in real data · zero hallucination
We project a win for the Arizona Diamondbacks with a 52% model probability. The primary drivers are 'Home Advantage' and 'Last 10 Games Form', both yielding a deltaPct of 2.5. However, a significant deficit in 'Starting Pitcher Matchup' at -3.1 remains the key swing risk, and with the edge against the market uncalculated, we acknowledge that our model does not beat the market in the long run.
Logistic-regression statistical model — predicts Miami Marlins vs Arizona Diamondbacks 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.
