Dear list,

 I have read the excellent slides "Assessing the precision of estimates of variance
components" from our master Douglas Bates : /lme4.r-forge.r-project.org/slides/2009-07-21-Seewiesen/4PrecisionD.pdf

I wonder whether the authors of lme4 intend to include some functions for computing the profiled deviance components (lprss and ldL2) in a next version of the package ? 


I am also interested in some references about these profiled deviance components (for instance I'd like to understand why [what does it mean that] ldL2 measures the complexity of the model and why [what does it mean that] lprss measures the fidelity to the data ?)

All the best,
Stéphane
