hydroeval.mare

hydroeval.mare(simulations, evaluation)

Mean Absolute Relative Error (MARE).

Calculation Details

\[E_{\text{MARE}} = \frac{\sum_{i=1}^{N} \left| e_i-s_i \right|} {\sum_{i=1}^{N} e_i}\]

where N is the length of the simulations and evaluation periods, e is the evaluation series, s is (one of) the simulations series.
