| istar-ergmTerm {ergm} | R Documentation |
This term adds one network statistic to the
model for each element in k . The i th such statistic counts the
number of distinct k[i] -instars in the network, where a
k -instar is defined to be a node N and a set of k
different nodes {O[1], ..., O[k]} such that the ties
(O_j, N) exist for j=1, …, k . If attr is specified
then the count is over the number of k -instars where all nodes have
the same value of the attribute. This term can only be used for directed
networks; for undirected networks see kstar . Note that
istar(1) is equal to both ostar(1) and edges .
