This term adds one network statistic to the model equal to the weighted
degree distribution with decay controlled by the decay parameter, which should be non-negative,
for nodes in the first mode of a bipartite network. The first mode of a bipartite network
object is sometimes known as the "actor" mode.
This term can only be used with undirected bipartite networks.
# binary: gwb1degree(decay, fixed=FALSE, attr=NULL, cutoff=30, levels=NULL)nonnegative decay parameter for the first mode degree frequencies; 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.
a vertex attribute specification (see Specifying Vertex attributes and Levels (?nodal_attributes) for details.)
This optional argument sets the number of underlying degree 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.)
