b1twostar-ergmTerm

InitErgmTerm.b1twostar

This term takes two nodal attributes. Assuming that there are
\(n_1\) values of <code>b1attr</code> among the b1 nodes and \(n_2\)
values of <code>b2attr</code> among the b2 nodes, then the total number of
distinct categories of two stars according to these two attributes is
\(n_1(n_2)(n_2+1)/2\). By default, this model term creates a distinct statistic
counting each of these categories.

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>.
