kge: Computes the Kling-Gupta efficiency coefficient.

In IvanHeriver/hsa-R-package: Hydrological Signature Analysis toolbox

Description

This function computes the Kling-Gupta efficiency coefficient. It islargely inspired by the similar function in the HydroGOF package. Here, only a simplified version is provided with no checks on inputs and very little formatting.

Usage

kge(obs, sim, na.rm = TRUE, method = 1)

Arguments

obs	numeric vector. Observed streamflow vector.
sim	numeric vector. Simulated streamflow vector.
na.rm	logical. Whether missing values should be ignored.
method	two methods are implemented (see hydroGOF::KGE): one from Gupta et al. (2009) and the other one from Kling et al. (2012)

Value

Returns a float value between -Inf and 1 corresponding to the Kling-Gupta efficiency coefficient.
