ergmx.altkstar

ergmx.altkstar(lambda_, fixed=False)

Alternating k-stars (Snijders et al. 2006) with weight lambda (undirected networks): sum over vertices of lambda^2 ((1 - 1/lambda)^d - 1 + d / lambda). Only with fixed=TRUE: ergm’s estimated version is not the same statistic, and ergm recommends gwdegree(), with edges the same model.
