This Coastal and Hydraulics Engineering Technical Note CHETN describes the statistical metrics used by the Wave Information Studies WIS and produced as part of the model evaluation process. The objective of the WIS is to provide coastal wave hindcast model estimations, wave analyses products, and decision support tools nationwide. These wave estimates are hindcast using high-quality climatology data and third-generation wave models. The resulting wave estimates height, period, and direction and directional spectral estimates are provided for a set of preselected, virtual gauge locations along the Pacific, Great Lakes, Gulf of Mexico, Atlantic, and Western Alaska coasts. One component of the evaluation process is the computation of summary statistics. These error statistics, or statistical metrics, include bias, root-mean-square error RMSE, scatter index, symmetric slope, and correlation coefficient.
