Hey hey hey,

Having thought a little about this discussion, I almost feel for initiating a dry study investigating some of the issues in this thread. It would be interesting to find out which approach performs better (if an objective measure of that can be defined) when there are missing period data for one or more subjects. In particular it would be great FUN (and of potential interest to the PK oracles at EMEA) to play around with imputation methods and see if it is possible to find an imputation approach that outperforms linear mixed effect models.

Comments?
