b2star-ergmTerm {ergm} | R Documentation |
-stars for the second mode in a bipartite network
Description
This term adds one network statistic to the model for
each element in k
. The th such statistic counts the number of
distinct
k[i]
-stars whose center node is in the second mode of the
network. The second mode of a bipartite network object is sometimes known as
the "event" mode. A -star is defined to be a center node
and
a set of
different nodes
such that the
ties
exist for
. This term can only be used for
undirected bipartite networks.
Usage
# binary: b2star(k, attr=NULL, levels=NULL)
Arguments
k |
a vector of distinct integers |
attr , levels |
a vertex attribute specification; if |
Note
b2star(1)
is equal to b1star(1)
and to edges
.
