Hierarchical exponential-family random graph models with local dependence can be specified by calling the function hergm(formula)
,
where formula is a formula of the form network ~ terms
.
By specifying suitable terms,
it is possible to specify a wide range of models: see hergm
.
hergm.terms
can be found here.
In addition, ergm.terms
can be used to include covariates.
adding the term edges_i
to the model adds node-dependent edge terms to the model;
please note: the term edges_i
can be used with method = "bayes"
but cannot be used with the default method = "ml"
.
adding the term arcs_i
to the model adds node-dependent outdegree terms to the model;
please note: the term arcs_i
can be used with method = "bayes"
but cannot be used with the default method = "ml"
.
adding the term arcs_j
to the model adds node-dependent indegree terms to the model;
please note: the term arcs_j
can be used with method = "bayes"
but cannot be used with the default method = "ml"
.
adding the term edges_ij
to the model adds block-dependent edge terms to the model.
adding the term mutual_i
to the model adds additive, block-dependent mutual edge terms to the model.
adding the term mutual_ij
to the model adds block-dependent mutual edge terms to the model.
adding the term twostar_ijk
to the model adds block-dependent two-star terms to the model;
adding the term transitiveties_ijk
to the model adds block-dependent transitive ties terms to the model.
adding the term triangle_ijk
to the model adds block-dependent triangle terms to the model.
adding the term ttriple_ijk
to the model adds block-dependent transitive triple terms to the model;
please note: the term ttriple_ijk
can be used with method = "bayes"
but cannot be used with the default method = "ml"
.
adding the term ctriple_ijk
to the model adds block-dependent cyclic triple terms to the model;
please note: the term ctriple_ijk
can be used with method = "bayes"
but cannot be used with the default method = "ml"
