Crpss skill score
WebFeb 25, 2010 · CRPSS is a proper measure of the overall ensemble forecast performance. It is the integral of the Brier skill score at all possible threshold values for continuous predictands. The CRPSS measures the skill relative to the reference forecast and is positively oriented. WebDescription. The Continuous Ranked Probability Skill Score (CRPSS; Wilks, 2011) is the skill score based on the Continuous Ranked Probability Score (CRPS; Wilks, 2011). It can be used to assess whether a forecast presents an improvement or worsening with respect to a reference forecast. The CRPSS ranges between minus infinite and 1.
