Results of our trust model evaluated on the close friendship network. Comparison of the performance of our trust model (TM) to that of a random model (RM) in approximating the true evolving nature of the friendship network over time. We compare the distributions in terms of three measures, (row 1) the Kullback–Leibler divergence (KL Div) (row 2) the Earth mover’s distance (EMD) and (row 3) the slope of the Quantile–Quantile–Plot (QQ plot). All results are averaged over 100 random trials of the stochastic process. In all cases except for (b), our TM for both (a) and (c) outperforms the baseline
