| logLik {base} | R Documentation |
This function is generic; method functions can be written to handle
specific classes of objects. Classes which already have methods for
this function include: lm, nls in package nls,
and gls, lme and others in package nlme.
logLik(object, ...)
object |
any object from which a log-likelihood value, or a contribution to a log-likelihood value, can be extracted. |
... |
some methods for this generic function require additional arguments. |
Returns an object, say r, of class logLik which is a
number with attributes, attr(r, "df") (degrees of
freedom) giving the number of parameters in the model.
There's a simple print method for logLik objects.
The details depend on the method function used; see the appropriate
documentation.
