TABLE I. Comparison of different models for many empirical networks. The columns in the table correspond to the data-set number (with the name given at the bottom of the table), the number of nodes N , the average degree h k i ¼ 2 E=N , and the posterior odds ratios relative to the best model for the degree-corrected overlapping ( Λ ), the degree-corrected nonoverlapping ( Λ ), non-degree- DCO DC corrected overlapping ( Λ ), and non-degree-corrected nonoverlapping ( Λ ) models. Missing entries correspond to situations NDCO NDC where the best overlapping partition turns out to be nonoverlapping. The last three columns show some parameters of the best model: the number of groups B , the average mixture size h d i , and the description length per edge (in bits per edge).
