ergmx.b1twostar

ergmx.b1twostar(b1attr, b2attr=None, base=None, b1levels=None, b2levels=None, levels2=None)

Number of two-stars centred on first-mode vertices, by the value of b1attr of the centre and the (unordered) values of b2attr of the two ends.

Bipartite networks only; b1 terms are about the first mode, b2 terms the second.
