The Institute of Statistical Mathematics aims to further develop statistics by promoting the exchange of data and resources between domestic and foreign researchers. This has been examined from a statistical viewpoint, which suggests using a new index whereby the progress and effectiveness of the joint use can be objectively assessed. We analyzed co-author information using betweenness centrality in articles written by researchers at the Institute of Statistical Mathematics in 2013, obtained from the Web of Science. The analysis results enable identification of the researched people that are in the center of their research field.
