To highlight what said, three curves with irregular points and a curve with anomalous data, in which the residuals distribution exhibits an unbalanced mean and a marked asymmetry due to the solely effect of the irregular data in the anomalous part (spotlighted), are reported in Fig. 9-11 and Fig. 12, respectively.
