Utilities
Interactive calculators for the arithmetic the odds pipeline leans on. Each tool seeds with a worked example, recomputes live as you type, and narrates its solver step by step — the same math the Odds Generation engine runs when it strips margins and back-solves goal rates.
Tools
| Tool | What it does |
|---|---|
| Poisson Calculator | Point, tail and range probabilities for a Poisson count — plus the inverse: hand it a target probability and it searches out the λ that produces it. |
| Margin — two-way (Power) | Strip a bookmaker margin from a priced two-way Malay pair, or apply a ladder MARGIN to a fair pair and snap to the 0.01 grid. |
| Margin — multi-way (Shin) | Strip or apply margin on markets with three or more outcomes via the Shin insider model — favourite-shaded, exact inverse round-trip. |
The pure math behind all three lives in docs/src/lib/odds/ and is pinned by
worked-example tests alongside the engine's golden-master suite.
