What Forecast expects · Favourite

79%ATLchance to win
ATL · 78.7%21.3% · POR
  • ATL starts with a 78.7% chance to win; POR with 21.3%.
  • In games: out of 10 like this one, ATL would win 8 and POR 2.

Confidence

medium
  • The model sees a clear favorite.
  • Research-stage model: shown as what it said before tip-off, not as an advantage.
  • The model does not know this game's injuries or starting five.

Why

  • The model looks at only two things: each team's accumulated season strength and home court.
  • Home court is worth 4.6 probability points to ATL.
  • ATL comes in with the stronger accumulated season form: that moves 24.1 points toward ATL.

What could flip it

  • The model does not read the injury report and has no players inside it: an absence would change the game without changing this number. There is no calculation saying by how much.
  • What the model does not look at and this number does not capture: rest and travel, the day's injury report, the starting five and recent form.

Uncertainty

  • The model gives a number, not a band: its reliability is measured by comparing forecasts with results, not by drawing a margin.
  • It does not know injuries, rest, travel or the starting five: any of them can move this game without the number changing.
  • For reference, the pre-tip market consensus gave ATL 85.9%.

this game's error
  • Expected: ATL at 78.7%.
  • Actual: ATL 83 – POR 101. POR won.
  • The model picked the wrong side.
  • We gave the winner only 21.3%: a big surprise for the model.
  • This game's error: 0.62 (0 = nailed it, 1 = worst possible; a 50% call would score 0.25).
  • The market consensus (14.1% on the winner) also picked the wrong side.
  • What we learn: on this game the model was closer to the result than the market consensus. One game is not a sample.

  • Over 47 settled games with this model: it picked the right side 74% of the time and its average error (Brier) was 0.173. When it said X%, reality was on average 13 points away from that X%.
  • On those same games, the market consensus had less error (0.172 versus 0.173): the model does not beat it, and we say so.
  • 47 games is a small sample: these numbers still move a lot.

How it is measured and limits

Model

SportiveWorld's WNBA game model, research stage: it reads each team's accumulated season strength and home-court advantage. Shown as what it said before tip-off, not as an edge.

This is the preview saved before the game, not current data.

Sample · Measured against 47 settled games.

Injuries · Availability known before tip-off: an injury report existed and was read (it does not enter the number).

  • · What you see is the preview sealed before the game, not a later recalculation.
  • · 47 games is a small sample: these numbers still move a lot.
