b1degrange-ergmTerm {ergm}

Degree range for the first mode in a bipartite network

Description

This term adds one network statistic to the model for each element of from (or to ); the ith such statistic equals the number of nodes of the first mode ("actors") in the network of degree greater than or equal to from[i] but strictly less than to[i] , i.e. with edge count in semiopen interval ⁠[from,to)⁠ .

This term can only be used with bipartite networks; for directed networks see idegrange and odegrange . For undirected networks, see degrange , and see b2degrange for degrees of the second mode ("events").

Usage

# binary: b1degrange(from, to=`+Inf`, by=NULL, homophily=FALSE, levels=NULL)

Arguments

from, to

vectors of distinct integers. If one of the vectors have length 1, it is recycled to the length of the other. Otherwise, it must have the same length.

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.
