odegrange-ergmTerm {ergm}

Out-degree range

Description

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

This term can only be used with directed networks; for undirected networks (bipartite and not) see degrange . For degrees of specific modes of bipartite networks, see b1degrange and b2degrange . For in-degrees, see idegrange .

Usage

# binary: odegrange(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.

attr

a vertex attribute specification (see Specifying Vertex attributes and Levels (?nodal_attributes) for details.)
