Table 2. The table describes the structural positions in the Main Component through the distribution of SMO attributes. The members of Block 4 are not strictly structurally equivalent, but a subset of heavy user groups from Block 3 (Ui ≥ 30). Note: [v] and [s] mean that the valued and symmetrical networks, respectively, were used for calculations; [1] and [2] mean that the user intensity was calculated with and without the outlier WWF, respectively. The number of missing data for each calculation is given within parenthesis (NaN).
