logLik.lmList {nlme} | R Documentation |
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.
