ergm.bridge.llr
uses bridge sampling with geometric spacing to
estimate the difference between the log-likelihoods of
two parameter vectors for an ERGM via repeated calls to
simulate.formula.ergm
.ergm.bridge.0.llk
is a convenience wrapper around ergm.bridge.llr
: returns the
log-likelihood of configuration `theta' relative to the reference
measure. That is, the configuration with theta=0 is defined as
having log-likelihood of 0
See also ergm.bridge.dindstart.llk
to use dyad-independent ERGM as a staring point.
