twopath-ergmTerm-930ae8af: 2-Paths

In ergm: Fit, Simulate and Diagnose Exponential-Family Models for Networks

2-Paths

Description

This term adds one statistic to the model, equal to the number of 2-paths in the network. For a directed network this is defined as a pair of edges (i{\rightarrow}j), (j{\rightarrow}k) , where i and j must be distinct. That is, it is a directed path of length 2 from i to k via j . For directed networks a 2-path is also a mixed 2-star but the interpretation is usually different; see m2star . For undirected networks a twopath is defined as a pair of edges \{i,j\}, \{j,k\} . That is, it is an undirected path of length 2 from i to k via j , also known as a 2-star.
