Nash Sutcliffe Efficiency of a model's output against observations

Share:

Description

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

Usage

1
NSE(qsim, qobs, digits = 2)

Arguments

qsim

Time series or vector of simulated values.

qobs

Time series or vector of observations.

digits

No. DP 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 regardred as "behavioural".
