Success Rate(SR)

SR is the fraction or percentage of success among a number of attempts. CLIK provides a simple success rate as the DMME verification score.

Anomaly Correlation Coefficient(ACC)

ACC is one of the most widely used measures in the verification of spatial fields and is the correlation between anomalies of forecasts and those of verifying values with the reference values, such as climatological values.

Heidke Skill Score(HSS)

HSS is commonly used skill score for the verification of categorical probabilistic forecast. Measuring the fractional improvement of the forecast over random forecast.

Relative Operating Characteristics(ROC) Curve

The ROC curve indicates the degree of correct probabilistic discrimination in a set of forecasts. Discrimination is the ability to distinguish one categorical outcome from another even if the forecast probabilities have biases or calibration problems.
