nashS {tiger} | R Documentation |
Calculates the Nash Suttcliffe Efficiency coefficient.
nashS(modelled, measured, weigth = NA) nashS_HF(modelled, measured, weigth = NA)
modelled |
Vector with modeled data |
measured |
Vector with measured data |
weigth |
If this vector is supplied, each data point is weighted accordingly |
The weighting corresponds to the value in the empirical cumulative distribution function.
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.
