Measures comparing cumulative distributions of angle to nearest neighbor <i>φ</i> in experiment (<i>EXP</i>), a social interaction model (<i>INT</i>) and a noninteracting control model (<i>NON</i>).

<p>By measures of the difference between median values , the Kolmogorov-Smirnov distance , and the Kullback-Leibler divergence , the cumulative distributions for <i>INT</i>, <i>NON</i>, and <i>EXP</i> are nearly identical. Since <i>φ</i> is an angle measured in radians, the values of should be compared to the value 2<i>π</i>. The three distributions are shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0083343#pone-0083343-g006" target="_blank">Fig. 6(B)</a>.
