Moreno Van de Bunt Freshman Network

A University freshman friendship survey (longitudinal) dataset of 32 nodes and 710 edges, collected by Van de Bunt et al.. Each record contains directed edges: True, weighted: True, signed: True. This directed network contains friendship ratings between 32 university freshmen who mostly did not know each other before starting university. Each student was asked to rate the other student at seven different time points. Note that the origin of the timestamps is not accurately known but the dis. Suitable for longitudinal social network analysis, friendship formation. The file holds 3,062 ratings, one row per rating in each survey wave; the edge count of 710 counts distinct pairs.
