One bookmaker as the model
Use one bookmaker’s implied probabilities as the predictor. This is not an aggregate: the selected book alone drives the calculated metrics.
Interquartile mean (Vetted List)
Default modelThe interquartile mean removes the outer quarters of the quoted probabilities, then averages the central half. It limits the influence of extreme prices.
Mean (Vetted List)
The arithmetic mean gives every included predictor equal influence. It is transparent and responsive, but more sensitive to outliers.
Median (Vetted List)
The median uses the central quoted probability. It is robust to isolated extremes and does not measure the distance between the remaining observations.
Margin-weighted mean (Vetted List)
The margin-weighted mean gives greater influence to bookmakers whose quoted market carries a smaller margin.
Recency-weighted mean (Vetted List)
The recency-weighted mean gives greater influence to prices that changed more recently, so the calculation responds to newer market information.
