Log-Likelihood of an lmList Object
Usage
logLik(object, REML, pool)
Arguments
object
|
an object inheriting from class lmList , representing
a list of lm objects with a common model.
|
REML
|
an optional logical value. If TRUE the restricted
log-likelihood is returned, else, if FALSE , the log-likelihood
is returned. Defaults to FALSE .
|
pool
|
an optional logical value indicating whether all lm
components of object may be assumed to have the same error
variance. Default is attr(object, "pool") .
|
Description
If pool=FALSE
, the (restricted) log-likelihoods of the lm
components of object
are summed together. Else, the (restricted)
log-likelihood of the lm
fit with different coefficients for
each level of the grouping factor associated with the partitioning of
the object
components is obtained.Value
either the sum of the (restricted) log-likelihoods of each lm
component in object
, or the (restricted) log-likelihood for the
lm
fit with separate coefficients for each component of
object
