Nash Sutcliffe Efficiency of a model's output against observations
Returns the the NSE (NSE, Nash and Sutcliffe, 1970) of the simulated values against the given observations.
NSE(qsim, qobs, digits = 2)
Time series or vector of simulated values.
Time series or vector of observations.
No. DP in returned 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".
