A Co-authorship network analysis of CNPq’s productivity research fellows in the probability and statistic area
Abstract In this paper, we analyzed the co-authorship network between all CNPq’s productivity research fellows in the Probability and Statistics area in Brazil. Our aim was to describe and to understand how network measures influence researchers’ productivity. The data was gathered from the CNPq’s L...
