Vaughan, maybe your data contain edge weights (e.g., tie strengths). In that
case, centralization is not constrained to 0 to 1 interval. The situation is
analogous to computing density. Density can be seen as the average value in
a graph's adjacency matrix. This average is between 0 and 1 when matrix
entries are 0s or 1s. When there are other values, the average is not
constrained ...
