[statnet_help] ERGMs for multilevel/multilayer networks

[Michał Bojanowski]

Hi!

Great!

For terms such as 'absdiff' you should be able to create a matrix of
abs(x_i - x_j) values and then put 0 everywhere but the dyads of
interest (e.g. only between humans) and use that matrix as input for
the 'dyadcov' term.
