A Weighted Statistical Network Modeling Approach to Product Competition Analysis

Figure 3

An overview of the 2013 and 2014 co-consideration network. (a) The blue nodes represent car models and black links represent co-consideration relations. The node size is proportional to the weighted degree of a car model, and the link width is proportional to the link strength of the co-consideration relation. And, an example of the local co-consideration network between three cars changing from 2013 to 2014 (b).
