Table 2 Parameters for undirected networks
From: Testing biological network motif significance with exponential random graph models
Effect | Description |
|---|---|
Edge | Baseline density |
A2P | Alternating k-two-paths. Used as a “control” for alternating k-triangles |
AS | Alternating k-stars. A positive parameter value indicates centralization based on high-degree nodes |
AT | Alternating k-triangles. A positive parameter value indicates network closure (triangles) |
Match c | Categorical matching on categorical attribute c. A positive parameter value indicates an edge preferentially forming between nodes with the same value of the categorical attribute (known as “homophily” in social network research) |
