public class RootRelativeSquaredError
extends AbstractPerformanceCounter

Relative squared error is the total squared error made relative to what the error would have been if the prediction had been the average of the absolute value. As done with the root mean-squared error, the square root of the relative squared error is taken to give it the same dimensions as the predicted values themselves. Also, just like root mean-squared error, this exaggerates the cases in which the prediction error was significantly greater than the mean error.
