Mixed models with missing data

Bone, Jonathan
Hi,

I am creating a mixed model based on a experiment where each subject has 2 repeats. In some instances though there is only data for one of a given subjects repeats for most there is data for both. Can I still justify having subject as a random effect?

Thanks,

Jonathan

This has basically nothing to do with R, so please don't post here.

You may wish to try the r-sig-mixed-models list, however. They are
more sympathetic to such questions -- and what are likely to be the
torrent from you that follows.
