Figure 7

Relative deviation as boxplot for the first five minutes. (a) corresponds to the new ANN. Here, we can see that the deviations are narrower concentrated in the middle interquartile ranges. (b) corresponds to the persistence model. 50% of the deviations are not exactly located in the middle. In addition, the 25% and 75% of the deviation is higher than in (a).
