Relative importance of reshuffling on .

<p>Analyzed elections and the manner that elections are divided into two groups are the same than in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0039916#pone-0039916-g006" target="_blank">Fig. 6</a>. Nevertheless, here, each election is aggregated at national scale, i.e. is directly evaluated from the set at the national scale. In these figures, surrogate data, consist in reshuffling from one election to another one in the same group, while is not modified. Surrogate curves result from the average of 1000 realizations, and standard-deviations are plotted as error bars.
