NSE: Nash Sutcliffe Efficiency of a model's output against...

In dynatopmodel: Implementation of the Dynamic TOPMODEL Hydrological Model

Description

Returns the the NSE (NSE, Nash and Sutcliffe, 1970) of the simulated values against the given observations.

Usage

NSE(qsim, qobs, digits = 2)

Arguments

qsim	Time series or vector of simulated values
qobs	Time series or vector of observations
digits	No. decimal places in returned value

Value

A number <= 1 indicating the goodness of fit of the simulated series against observations (1= perfect fit). Values of >0.8 are generally regarded as "behavioural"
