This term adds one statistic for every possible nonzero distinct
value of abs(attr[i]-attr[j]) in the network. The value of each such
statistic is the number of edges in the network with the corresponding
absolute difference.

specifies which nonzero difference to include in or exclude from the model. (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.
