I am currently using several SNA tools including R to analyze the data. Eventually, I will use R because it can compute weighted network. However, the results from R are different from other tools in terms of computing betweenness and closeness centralities.
In fact, the basic centrality scores from all tools are different except for the degree centrality. I am just wondering what algorithm R uses for computing betweenness and closeness centrality. I don’t expect R developers (experts) to know how other tools compute the centrality measures, but is there any possible explanation of why SNA tools produce different results? I would like to know what causes this issue and any solution for this. Thank you! Jinie
