LADDER SCOREBOARD Updated

History

How teams' actual and projected ladder finish changed over time.

Adelaide Brisbane Lions Carlton Collingwood Essendon Fremantle Geelong Gold Coast Greater Western Sydney Hawthorn Melbourne North Melbourne Port Adelaide Richmond St Kilda Sydney West Coast Western Bulldogs
Season In Progress: Scores below are marked against the current ladder. Models may rapidly gain or lose points as the ladder changes and past projections become better or worse in retrospect.

Accuracy

How closely each model's weekly projections matched the final ladder (or, for a season in progress, the current ladder). Higher scores are better.

"Ladder" is a prediction that every team remains in the same ladder position, with 100% probability.

Ladders include results from the nominated round. For example, a Round 1 ladder was made after Round 1, not before. Preseason ladder predictions are "Round -1" in years with an "Opening Round" and "Round 0" otherwise.

Accuracy is determined by Rank Probability Score, a proper scoring rule that rates the accuracy of forecasts that comprise a range of probabilities. Since the result is often a very small number — less than 0.1 for good forecasts — it is scaled with SCORE = 50 * (1 - RPS) - 40 so that a perfect score is 10.0.

Each model's total score is a sum of its round scores. Previously, an average was used instead, but that unfairly benefited models who failed to submit predictions in the early rounds.
