Name: Coefficient of variation root mean square error (CV(RMSE))
Alternative names: CV(RMSD)
Definition:

Measure of the differences between values predicted by a model or an estimator and the mean of the values actually observed.

CV(RMSE) = RMSE / MEAN

where MEAN = the mean of the observed values
