asymmetric-ergmTerm-da585369: Asymmetric dyads

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

Asymmetric dyads

Description

This term adds one network statistic to the model equal to the number of pairs of actors for which exactly one of (i{\rightarrow}j) or (j{\rightarrow}i) exists.

Usage

# binary: asymmetric(attr=NULL, diff=FALSE, keep=NULL, levels=NULL)

Arguments

attr	quantitative attribute (see Specifying Vertex attributes and Levels (?nodal_attributes) for details.) If specified, only symmetric pairs that match on the vertex attribute are counted.
diff	Used in the same way as for the nodematch term. (See nodematch (ergmTerm?nodematch) for details.)
keep	deprecated
level	Used in the same way as for the nodematch term. (See nodematch (ergmTerm?nodematch) for details.)

Note

This term can only be used with directed networks.

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