This term adds one network statistic to the model equal to the geometrically
weighted dyadwise shared partner distribution for dyads in the second bipartition with decay parameter
decay parameter, which should be non-negative. This term can only be used with bipartite networks.
# binary: gwb2dspL(decay=0, fixed=FALSE, cutoff=30, Ls.path=NULL)nonnegative decay parameter for the shared partner counts; required if fixed=TRUE and ignored with a warning otherwise.
optional argument indicating
whether the decay parameter is fixed at the given value, or is to be fit as a curved
exponential-family model (see Hunter and Handcock, 2006). The
default is FALSE , which means the scale parameter is not
fixed and thus the model is a curved exponential family.
This optional argument sets the number of underlying b2dsp terms
to use in computing the statistics when fixed=FALSE, in order to reduce
the computational burden. Its default value can also be controlled by the
gw.cutoff term option control parameter. (See ?control.ergm.)
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.)
