Calculate the null model likelihood
logLikNull(object, ...)# S3 method for ergm
logLikNull(object, control = control.logLik.ergm(), ...)
a fitted model.
further arguments to lower-level functions.
logLikNull computes, when possible the log-probability of
the data under the null model (reference distribution).
A list of control parameters for algorithm tuning.
Constructed using control.logLik.ergm.
logLikNull returns an object of type logLik if it is
able to compute the null model probability, and NA otherwise.
ergm: A method for ergm fits; currently only
implemented for binary ERGMs with dyad-independent sample-space
constraints.
