This term adds one network statistic to the model, equal to the number of nodes in the first mode of the network with degree 2 or higher. The first mode of a bipartite network object is sometimes known as the "actor" mode. This term can only be used with undirected bipartite networks.
# binary: b1concurrent(by=NULL, levels=NULL)
optional argument specifying a vertex attribute (see Specifying
Vertex attributes and Levels (?nodal_attributes
) for details).
It functions just like the by
argument of the b1degree
term.
Without the optional argument, this statistic is equivalent to b1mindegree(2)
.
