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