Dear R.S. Cotter,
I think that interpretation of R2 is not straightforward and it is area
of research.. Have a look to
Xu. Measuring explained variation in linear mixed effects models
Statist. Med. 2003; 22:3527?3541 (DOI: 10.1002/sim.1572)
Orelien, J.G., Edwards, L.J., Fixed-effect variable selection in linear
mixed models using R2 statistics Comput. Statist.
Data Anal. (2007), doi: 10.1016/j.csda.2007.06.006
Hope this helps you,
vito
