All,

The glmm wiki

http://glmm.wikidot.com/faq

gives examples for computing confidence intervals and prediction intervals
for normal mixed models. Can anyone give (ideally page numbers) references
for a text describing these expressions.

I'd love to know too!

  I haven't looked in the standard places (Pinheiro and Bates, 
Searle et al, Stroup, Demidenko, Galecki and Burzykowski ... ) but
don't remember seeing a reference -- these are just taken from
linear model theory or are common-sense extensions ...
