ergmx.Persist

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

tergm’s persistence model: formula evaluated on the intersection of the previous and the current network, the ties that persisted, which only changes when ties dissolve. A positive coefficient means less dissolution. 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().
