A Weighted Statistical Network Modeling Approach to Product Competition Analysis

Figure 5

Receiver operating characteristics (ROC) curves comparing the valued ERGM model with binary ERGM models with different cutoff values for network binarization on the 2014 car competition network. We observe that irrespective of what cutoff value is used, valued ERGM models have higher precision and recall values than other models: (a) cutoff = 1.0, (b) cutoff = 2.0, and (c) cutoff = 4.0.
