b1degree-ergmTerm {ergm}

Degree for the first mode in a bipartite network

Description

This term adds one network statistic to the model for each element in d ; the ith such statistic equals the number of nodes of degree d[i] in the first mode of a bipartite network, i.e. with exactly d[i] edges. The first mode of a bipartite network object is sometimes known as the "actor" mode.

Usage

# binary: b1degree(d, by=NULL, levels=NULL)

Arguments

d

a vector of distinct integers.

by, levels, homophily

the optional argument by specifies a vertex attribute (see Specifying Vertex attributes and Levels (?nodal_attributes) for details). If this is specified and homophily is TRUE , then degrees are calculated using the subnetwork consisting of only edges whose endpoints have the same value of the by attribute. If by is specified and homophily is FALSE (the default), then separate degree range statistics are calculated for nodes having each separate value of the attribute. levels selects which levels of by' to include.

Note

This term can only be used with undirected bipartite networks.
