b1star-ergmTerm-24b65fe7: k-stars for the first mode in a bipartite network

In ergm: Fit, Simulate and Diagnose Exponential-Family Models for Networks

k-stars for the first mode in a bipartite network

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] -stars whose center node is in the first mode of the network. The first mode of a bipartite network object is sometimes known as the "actor" mode. A k -star is defined to be a center node N and a set of k different nodes \{O_1, \dots, O_k\} such that the ties \{N, O_i\} exist for i=1, \dots, k. This term can only be used for undirected bipartite networks.

Usage

# binary: b1star(k, attr=NULL, levels=NULL)

Arguments

k	a vector of distinct integers
attr, levels	a vertex attribute specification; if attr is specified, then the count is over the instances where all nodes involved have the same value of the attribute. levels specified which values of attr are included in the count. (See Specifying Vertex attributes and Levels (?nodal_attributes) for details.)

Note

b1star(1) is equal to b2star(1) and to edges .
