However, negative indicators in Pythagorean Expectation and Last 10 Games Form suggest caution, and our model does not consistently outperform the market in the long run.
Logistic-regression statistical model — predicts Arizona Diamondbacks vs Colorado Rockies 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.
