This term adds a single network statistic for each quantitative attribute or matrix column to the model equaling the total
value of attr(j) for all edges \((i,j)\) in the network. This
term may only be used with directed networks. For categorical attributes,
see nodeifactor .
# binary: nodeicov(attr)# valued: nodeicov(attr, form="sum")
a vertex attribute specification (see Specifying Vertex attributes and Levels (?nodal_attributes) for details.)
how to aggregate tie values in a valued ERGM: "sum"
(the default) for a statistic of the form \(\sum_{i,j} x_{i,j}
y_{i,j}\), where \(y_{i,j}\) is
the value of dyad \((i,j)\) and \(x_{i,j}\) is the
term's covariate associated with it; and "nonzero" with the
edge considered to be present if its value is not 0. See
ergmTerm for more information.
