nodesqrtcovar-ergmTerm

This term adds one statistic equal to
\(\sum_{i,j&lt;k} y_{i,j}y_{i,k}/(n-2)\) . This can be
viewed as a valued analog of the <code>star(2)</code> statistic.

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 (2021) <arXiv:2106.04997>.

nodecovar-ergmTerm function

<dl><dt>center</dt>
<dd>If <code>center=TRUE</code> , the \(y_{\cdot,\cdot}\) s are
centered by their mean over the whole network before the
calculation. Note that this makes the model non-local, but it may
alleviate multimodailty.</dd>
<dt>transform</dt>
<dd>If <code>transform="sqrt"</code> ,
\(y_{\cdot,\cdot}\) s are repaced by their square roots before the
calculation. This makes sense for counts in particular. If
<code>center=TRUE</code> as well, they are centered by the mean of the
square roots.</dd></dl>
