Return, via logLik
or a custom S3 method, the (quasi)
log likelihood of a regression object.

This function is used by cpr
and cnr
to determine the
(quasi) log likelihood returned in the cpr_cpr
and cpr_cnr
objects.
Generally this function defaults to logLik
. Therefore, if an S3
method for determining the (quasi) log likelihood exists in the workspace
everything should work. If an S3 method does not exist you should define
one.
See methods(loglikelihood)
for a list of the provided methods. The
default method uses logLik
.
