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.

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.

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.

RRMSE (relative root mean squared error) is defined as
SD ratio was estimated as 0.5549, RMSE was calculated as 1.1802,
RRMSE 6.3838 and I as 3.4884.
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.
