ergmx.Change(formula, lm=None, subset=None, weights=None, contrasts=None, offset=None, label=None)

tergm’s change model: formula evaluated on the network of the dyads that changed between the previous and the current network. lm, as in N(), makes the coefficients vary between transitions, with the attributes .Time, .TimeID and .TimeDelta as well as the networks’ own (see ergmx.NetSeries()); subset, offset and label are those of N().
