KGE: Kling-Gupta Efficiency in hydroGOF: Goodness-of-Fit …
WebThe KGE is a normalized, dimensionless, model efficiency that measures general agreement. It presents accuracy, precision, and consistency components. It is symmetric (invariant to predicted observed orientation). It is positively bounded up to 1. The closer to 1 the better. For the formula and more details, see online-documentation References WebNov 1, 2024 · The Kling-Gupta efficiency (KGE), which combines the three components of Nash-Sutcliffe efficiency (NSE) of model errors (i.e. correlation, bias, ratio of variances or … teaching stem in elementary

WebOriginally proposed by , Kling–Gupta efficiency has been used in various fields. The bias, α (see Equation (20)), is calculated by dividing the standard deviation of the simulated variable by the standard deviation of the observed variable. Another bias, β (see Equation (21)), is calculated by dividing the mean of the simulated variable by ... WebAug 2, 2024 · The KGE' is an expression of distance away from the point of ideal model performance in the space described by its three components (correlation, variability bias and mean bias). KGE' = 1 indicates perfect agreement between simulations and observations. KGE' score for a mean flow benchmark is KGE'≈−0.41. WebMar 21, 2024 · The sensitivity analysis led us to identify fifteen influential parameters, which were selected for calibration. The optimized parameters gave the best model performance on the basis of the high Nash–Sutcliffe Efficiency (NSE), Kling–Gupta Efficiency (KGE), and determination coefficient (R 2 ). teaching stewardship to children
