Guidance on Setup, Calibration, and Validation of Hydrodynamic, Wave, and Sediment Models for Shelf Seas and Estuaries

Table 4

Example statistics to demonstrate the level of agreement between measured/observed data and model prediction.

Quality index	Example	Formulae
Accuracy	Root mean square error
Bias	Average bias
Correlation	Pearson product-moment coefficient: and
Skill	Brier skill score (BSS): Xp is the postevent condition predicted by the model, Xm is the measured postevent condition, and Xb is the preevent condition. Skill: index of agreement [44], where X and are time series and time average of model and observed values
		Agreement	Scatter index
