Computed similarity of individuals with different levels of social interaction.

<p>The computed similarity is shown as function of the parameter <i>α</i>, which tunes the weight of the individual links in the networks. The case <i>α</i> = 0 corresponds to the case of links having equal weight, whereas increasing values of <i>α</i> enhances the contribution from the stronger links in the calculation, e.g., for <i>α</i> = 2 the strongest links of each individual dominates. The envelope is the estimate of the standard deviation (see text). In <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0157436#pone.0157436.s003" target="_blank">S3 Text</a>, a table is included of p-values for the individual traits and for different <i>α</i>-values. In general, the p-values are large (>0.05) for the traits Conscientiousness, Agreeableness, Neuroticism and Openness. The estimates of Extraversion attains lower p-values, e.g. for the BlueTooth, <i>p</i> ≈ 0.01, and for SMS the p-value varies in the interval 0.02 − 0.08 for different <i>α</i>-values.
