[R-sig-ME] A question about LME4

[Subhash.Chandra at ecodev.vic.gov.au]

Appreciate your help and advice on (hopefully a simple) question. This 
relates to the mathematical expressions that LME4 uses to estimate log 
likelihood under maximum likelihood (ML) and under residual maximum 
likelihood (ReML) for fitting linear mixed models (LMM). What I am 
'exactly' looking for is mathematical expressions for log likelihood in 
the form of expressions (2), (4) and (5) in the attached paper by Gurka 
(2006).
 


I have gone through the LME4 documentation
https://cran.r-project.org/web/packages/lme4/vignettes/lmer.pdf
https://cran.r-project.org/web/packages/lme4/vignettes/Theory.pdf

I must admit I am unable to figure out the answer to my question. 

Regards,
Subhash
