Dear colleagues, I have a network of 130 countries with weighted interactions between them. I am calculating vertex betweenness to rank countries by betweenness, and get back non-integer values for each vertex (both in the weighted and unweighted case). Reading that "The vertex and edge betweenness are (roughly) defined by the number of geodesics (shortest paths) going through a vertex or an edge" I would expect integer values as result, or do I get something wrong?
Best, Thomas
