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
.
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.
