Synthetic sport adapter

Baseball

Inning-style run production for synthetic baseball.

Model baseball-innings v1.1.0 · family inning-sequence

Simulation settings

baseball-innings v1.1.0 · every run is a pure function of these inputs and the seed.

Sample

SeedSame seed and settings always reproduce this run.

IterationsEvents simulated. Observed frequency converges on the model as this grows.

Market

Odds sourcePrice from the model, or supply the board yourself and study how the model disagrees with it.

Margin %Overround the pricing model loads onto the fair line.

Pricing noise %± random error the market makes about the true probability before margin.

De-vig methodHow the margin-adjusted column removes the overround. Methods disagree most on the longest price.

Performance model

Home expected runsPoisson rate for the home side. Raising both rates lowers the draw share.

Away expected runsPoisson rate for the away side. The gap between the two rates drives the moneyline.
