Regional Climate Models

Other criteria

ĄBias = (forecasted occurrences) / (actual occurrences) = (H + F) / (H + M)

Ąranges 0 to infinity; ideally = 1

ĄProbability of detection = H / (H + M)

Ąranges 0 to 1; ideally = 1

ĄFalse alarm rate (aka probability of false detection) = F / (F + O)

Ąranges 0 to 1; ideally = 0

Probability of detection and false alarm rate are sometimes combined to produce the relative operating characteristic
