istar-ergmTerm {ergm}R Documentation

In-stars

Description

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 .
