The Relative Errors REs for the back-transformed estimate \({\hat{d}}_i\) and cross-validation trials. (a) The absolute value of the RE (% Relative Error) for the back-transformed estimate \(\hat{d_i}={[\widehat{\sqrt{(}d_i)}}]^2\) (b) The absolute value of the RE for the 20 “Leave-one-out cross-validation” (LOOCV) trials
