gwidegree-ergmTerm

InitErgmTerm.gwidegree

This term adds one network statistic to the model
equal to the weighted in-degree distribution with decay parameter
<code>decay</code> parameter, which should be non-negative. This
term can only be used with directed networks.

An integrated set of tools to analyze and simulate networks based on exponential-family random graph models (ERGMs). 'ergm' is a part of the Statnet suite of packages for network analysis. See Hunter, Handcock, Butts, Goodreau, and Morris (2008) <doi:10.18637/jss.v024.i03> and Krivitsky, Hunter, Morris, and Klumb (2023) <doi:10.18637/jss.v105.i06>.

gwidegree-ergmTerm function

<dl><dt>decay</dt>
<dd>nonnegative decay parameter for the indegree frequencies; required if <code>fixed=TRUE</code> and ignored with a warning otherwise.</dd>
<dt>fixed</dt>
<dd>optional argument indicating
whether the <code>decay</code> parameter is fixed at the given value, or is to be fit as a curved
exponential-family model (see Hunter and Handcock, 2006). The
default is <code>FALSE</code> , which means the scale parameter is not
fixed and thus the model is a curved exponential family.</dd>
<dt>attr</dt>
<dd>a vertex attribute specification (see Specifying Vertex attributes and Levels (<code>?nodal_attributes</code>) for details.)</dd>
<dt>cutoff</dt>
<dd>This optional argument sets the number of underlying degree terms
to use in computing the statistics when <code>fixed=FALSE</code>, in order to reduce
the computational burden. Its default value can also be controlled by the
<code>gw.cutoff</code> term option control parameter. (See <code>?control.ergm</code>.)</dd>
<dt>levels</dt>
<dd>TODO (See Specifying Vertex
attributes and Levels (<code>?nodal_attributes</code>) for details.)</dd></dl>
