This term adds one network statistic to the model for each element in d
; the \(i\) th
such statistic equals the number of dyads in the second bipartition with exactly
d[i]
shared partners. (Those shared partners, of course, must be members
of the first bipartition.) This term can only be used with bipartite networks.
# binary: b2dspL(d, Ls.path=NULL)
a vector of distinct integers
a vector of one or two formulas Ls.path
provides the Layer Logic (c.f. Layer Logic section in the
Layer()
documentation) specifications for the ties of the
2-path or the shared partnership. (If only one formula is given
the layers are assumed to be the same.) If L.in_order==TRUE
,
the first tie of the two-path must be the first element of
Ls.path
and the second must be the second; otherwise, any
ordering counts, provided there is exactly one of each. (For
types "OSP"
and "ISP"
, the first tie is considered to be the
one incident on the tail of the base tie.)
