Calculate the null model likelihood
logLikNull(object, ...)# S3 method for ergm
logLikNull(object, control = control.logLik.ergm(), ...)
logLikNull returns an object of type logLik if it is
able to compute the null model probability, and NA otherwise.
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,
typically constructed with control.logLik.ergm(). Its documentation
gives the the list of recognized control parameters and their
meaning. The more generic utility snctrl() (StatNet ConTRoL)
also provides argument completion for the available control
functions and limited argument name checking.
logLikNull(ergm): A method for ergm fits; currently only
implemented for binary ERGMs with dyad-independent sample-space
constraints.
