If you have one value in your sample, there’s no need to add anything. The formula just becomes:Brier score = (Actual result – Forecast Probability) But if you have several samples, you’ll want to calculate the squared differences (ft –ot)2 first, then add those up, and then ...
There is a sizeable literature on how best to measure accuracy (Maher 1993; Joyce 1998; Fallis 2007; Kopec 2012), and, in particular, whether it requires the use of a so-called proper scoring rule, such as the squared error or “Brier score” (Brier 1950). This question can be set...
The users' threshold probabilities for deciding to go to the beach thus approximately define their distribution of cost/loss ratios. This is used to calculate a 'User Brier Score' (UBS): a measure of the overall utility to society, and which could be used to guide forecast system development...
