Calculates the (weighted) Nash Suttcliffe Efficiency coefficient

Description

Calculates the Nash Suttcliffe Efficiency coefficient.

Usage

nashS(modelled, measured, weigth = NA)
nashS_HF(modelled, measured, weigth = NA)

Arguments

modelled Vector with modeled data
measured Vector with measured data
weigth If this vector is supplied, each data point is weighted accordingly

Details

The weighting corresponds to the value in the empirical cumulative distribution function.

Value

Returns a scalar between -Inf and 1 corresponding to the agreement between measured and modelled data. 0 means the model agrees equally well as the mean value.
