sociality-ergmTerm {ergm}

Undirected degree

Description

This term adds one network statistic for each node equal to the number of ties of that node. For directed networks, see sender and receiver .

Usage

# binary: sociality(attr=NULL, base=1, levels=NULL, nodes=-1)

# valued: sociality(attr=NULL, base=1, levels=NULL, nodes=-1, form="sum")

Arguments

attr, levels

this optional argument is deprecated and will be replaced with a more elegant implementation in a future release. In the meantime, it specifies a categorical vertex attribute (see Specifying Vertex attributes and Levels (?nodal_attributes) for details). If provided, this term only counts ties between nodes with the same value of the attribute (an actor-specific version of the nodematch term), restricted to be one of the values specified by (also deprecated) levels if levels is not NULL .

base

deprecated

nodes

By default, nodes=-1 means that the statistic for the first node will be omitted, but this argument may be changed to control which statistics are included just as for the nodes argument of sender and receiver terms.

form

Note

The argument base is retained for backwards compatibility and may be removed in a future version. When both base and levels are passed, levels overrides base.

This term can only be used with undirected networks.
