e

Description

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

Usage

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.
