Average error, average absolute error (AAE) and relative root mean square error (RRMSE).
Under the condition of not considering the underestimation for one of the most extreme flood flows during 24 months, the RRMSE values of ANN prediction model in this study for 1-, 3-, 6-, 12-, and 24-month-ahead forecasts in the YARHR are 16.84%, 19.89%, 22.88%, 19.17%, and 23.37%, respectively.

Average error, average absolute error (AAE) and relative root mean square error (RRMSE) Statistics Norway (SN), the Ministry of Finance (Fin) and Norges Bank (NB).
(11) RRMSE (relative root mean square error) is defined as [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] where [y.sub.n], represents the actual growth rate and [y.sub.n] is the projected growth rate.
The forecast error for consumer price inflation is virtually the same for all three institutions, but Statistics Norway has consistently been slightly closer to the mark than the other institutions, as measured by RRMSE. Norges Bank's projections for wage growth have been the most accurate.
(3) RRMSE (average relative error percentage) is defined as [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] where [y.sub.n] represents the actual growth rate and [y.sub.n] is the projected growth rate.

We begin with evidence obtained from RRMSE: the RRMSE <1 for 12 of 21 countries.
RRMSE [5, 51-53] normalizes daily precipitation RMSE by the mean daily precipitation of the gauge stations.
