Description

This page describes the network sample space constraints that are included with the tergm package. For more information, and instructions for using constraints, see ergm-constraints and ergm.

Constraints implemented in the tergm package

atleast(nw)

The Formation Constraint: Preserve all ties in network nw. Only dyads that are not ties in nw may be changed.

atmost(nw)

The Dissolution Constraint: Prevent all nonties in network nw. Only dyads that have ties in nw may be changed.
