sender-ergmTerm-e4dff00f: Sender effect

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

Sender effect

Description

This term adds one network statistic for each node equal to the number of out-ties for that node. This measures the activity of the node. The term for the first node is omitted by default because of linear dependence that arises if this term is used together with edges , but its coefficient can be computed as the negative of the sum of the coefficients of all the other actors. That is, the average coefficient is zero, following the Holland-Leinhardt parametrization of the $p_1$ model (Holland and Leinhardt, 1981).

For undirected networks, see sociality .

Usage

# binary: sender(base=1, nodes=-1)

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

Arguments

base	deprecated
nodes	specify which nodes' statistics should be included or excluded (see Specifying Vertex attributes and Levels (?nodal_attributes) for details)
form	character how to aggregate tie values in a valued ERGM

Note

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

This term can only be used with directed networks.
