Description

Calculates the Nash-Sutcliffe modelling efficiency (E) from observed and predicted values.

Usage

e(observed, predicted)

Arguments

observed	Numeric vector of observed values
predicted	Numeric vector of predicted values. The length shall be the same as for observed.

Details

E = 1 - sum(observed - predicted)/sum(observed - mean (observed))

Value

The Nash-Sutcliffe modelling efficiency (E) calculated from observed and predicted values.
