Abstract:

The Link Probability Model LPM can be used as an alternative to Exponential Random Graph Models ERGM to simulate network data. The LPM characterizes the networks in terms of link probabilities based on historical frequencies. In this paper, the LPM is presented, compared and contrasted with the ERGM. The relative utility of the two approaches is examined by applying both to four longitudinal data sets. The relative strengths and weaknesses of the two approaches in terms of data requirements, scalability, and assumptions are described.
