It was proposed by Glenn W. Brier in 1950. [1] The Brier score can be thought of as a cost function. More precisely, across all items in a set of N predictions, the Brier score measures the mean squared difference between: The predicted probability assigned to the possible outcomes for item i. The actual outcome.
While they have useful mathematical properties, they can produce counter-intuitive results: an event with an 80% probability of occurring is four times more likely to happen than an event with a 20% probability, but the odds are 16 times higher on the less likely event (4–1 against, or 4) than on the more likely one (1–4, or 4–1 on, or 0.25).
The player with the most accurate predictions wins the top prize, or a share of it if more than one player has these predictions. In addition, there is a special £3,000,000 prize or share of it for correctly predicting the nine score draws (draws of 1-1 or higher) when these are the only score draws on the coupon. [1]
