skill score

Statistics

A measurement of the skill of a forecast. The Priestley skill score, P, applies to value forecasts (such as forecasts of temperature). Let f_i denote a forecast, and let o_i denote the subsequent observed value, with o¯ denoting the mean of a set of n observed values. Then P is given by $skill score$ The Brier score was introduced in 1950 to assess the accuracy of probabilistic weather forecasts (e.g. ‘There is a probability p_i of rain tomorrow’). Denoting the actual weather outcome by o_i (equals 1 if the event occurs, and 0 if it does not) the Brier score, B, is given (for n forecasts) by $skill score$ The smaller the value of B, the more skilful the forecasting procedure. If B_s denotes the Brier score for a standard forecasting system, then S, given by $skill score$ is called the Brier skill score.
