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

Two-star census for central nodes centered on the first mode of a bipartite network

Description

This term takes two nodal attributes. Assuming that there are n_1 values of b1attr among the b1 nodes and n_2 values of b2attr among the b2 nodes, then the total number of distinct categories of two stars according to these two attributes is n_1(n_2)(n_2+1)/2. By default, this model term creates a distinct statistic counting each of these categories.

Usage

# binary: b1twostar(b1attr, b2attr, base=NULL, b1levels=NULL, b2levels=NULL, levels2=NULL)

Arguments

b1attr	b1 nodes (actors in some contexts) (see Specifying Vertex attributes and Levels (?nodal_attributes) for details)
b2attr	b2 nodes (events in some contexts). If b2attr is not passed, it is assumed to be the same as b1attr .
b1levels, b2levels, base, levels2	used to leave some of the categories out (see Specifying Vertex attributes and Levels (?nodal_attributes) for details)

Note

The argument base is retained for backwards compatibility and may be removed in a future version. When both base and levels are passed, levels overrides base.
