Mean number of the four closed triples for nodes with the same indegree in the Epinions social network and the model.
Results for the mean number of closed triples corresponding to (a) , (b) , (c) , and (d) loops for nodes with the same indegree are shown for the Epinions social network (black squares) and simulated network (red circles) based on the model. Analytic treatment (see Eq. (28)) gives a scaling behavior with an exponent , as indicated by the dash lines. Data points are averages over the logarithmic bins of the indegree .
