Witryna20 sie 2024 · The Nash-Sutcliffe coefficient of efficiency E, is commonly used to assess the performance of rainfall runoff models. Where O are the observed values and M are the modelled values. The maximum values of E is 1. A value of zero indicates that the model is only as good as using the mean of the observations. E can be less than zero.
