WebFeb 1, 2024 · Gupta et al. (2009) showed that optimizing αNSE underestimates the variability of simulated flows because the optimum NSE is attained when αNSE = r. In view of this, Gupta et al. (2009) and Kling et al. (2012) recommended the Kling-Gupta efficiency (KGE) in order to circumvent the connections between the variation coefficient and bias and ratios. WebAug 2, 2024 · The Kling-Gupta Efficiency (KGE) The KGE metric differs from the NSE metric in that it is not derived from the MSE; KGE is simply the Euclidean distance computed using the coordinates of bias, standard deviation, and correlation (Gupta et al., 2009).
