Residual maps for TN and TP. Residuals are computed using the testing sub-dataset (observations minus predictions). In each maps is also reported the \({{\rm{RMSE}}}_{te}^{or}\) for the testing sub-daset in ppm, \({{\rm{RMSE}}}_{te.ld}^{or}\) and \({{\rm{RMSE}}}_{te.hd}^{or}\) using observation in the low/high density, respectively.
