Probabilities, not certainties. How they are made: the methodology.

Was this pick made in advance?

A model whose name ends -oos is out of sample: it was fitted only on matches played before this one, so its pick is a genuine forecast rather than hindsight. Anything without that suffix was fitted on all available data.

What the model said

Model	Home / Draw / Away	Expected goals	Likeliest score	O2.5	BTTS
serve-hold	84016	13.28–9.34	2-0 55%	43%	0%

A model whose name ends -oos was produced by the walk-forward backtest: it was fitted only on matches played before this one, so the pick is genuinely out of sample.

Using this section

Every selection the model prices for this fixture, grouped by family — click a heading to open it. Calibrated is the number to read; lift shows how far it sits from what that selection normally does in this league. To compare selections across fixtures instead, use the Radar.

All markets

Every selection below comes from the same scoreline distribution, so they are mutually consistent rather than independently guessed. Calibrated is the model corrected by its own out-of-sample record; lift is how much more likely that is than the selection simply being true in this league anyway.
