b2sociality-ergmTerm-ae7e4336: Degree

In ergm: Fit, Simulate and Diagnose Exponential-Family Models for Networks

Degree

Description

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

Usage

# binary: b2sociality(nodes=-1)

# valued: b2sociality(nodes=-1, form="sum")

Arguments

nodes

By default, nodes=-1 means that the statistic for the first node (in the second bipartition) will be omitted, but this argument may be changed to control which statistics are included. The nodes argument is interpreted using the new UI for level specification (see Specifying Vertex Attributes and Levels (?nodal_attributes) for details), where both the attribute and the sorted unique values are the vector of vertex indices (nb1 + 1):n , where nb1 is the size of the first bipartition and n is the total number of nodes in the network. Thus nodes=120 will include only the statistic for the 120th node in the second biparition, while nodes=I(120) will include only the statistic for the 120th node in the entire network.

Note

This term can only be used with undirected bipartite networks.
