Calculating F values for lme function
Ricardo: You may do better posting on the r-sig-mixed-models list, which is specifically devoted to such topics. FWIW, re calculating F-values for mixed effects models, I think many say: don't.

You should use Reply-All to make sure the discussion continues to include the mailing list. Have you looked at the help for lme? lme is non-trivial, so it may take some reading. I only have a few of the references listed in the help file, and none with me at the moment. On January 15, 2019 7:36:22 AM PST, RICARDO ALVARADO BARRANTES < RICARDO.ALVARADO at ucr.ac.cr> wrote:
Thanks for your response, however my understandig of all this programming is very limited. Is there any source where I can read about F calculation for those models? Thanks for your time Ricardo El 14-01-2019 16:47, Jeff Newmiller escribi?:
Fortunately, nlme is open source [1 [1]][2 [2]], so you can follow
along in as much detail as you like.
Note that capitalization matters in R... NLME is not correct. [1] https://github.com/cran/nlme/blob/master/R/lme.R [2] https://cran.r-project.org/package=nlme On January 14, 2019 1:59:29 PM PST, RICARDO ALVARADO BARRANTES

I have a question related to the funcion LME in the library NLME. I would like to understand how the F values are calculated, since the output only shows the degrees of freedom but doen't show the sums of squares involved in those calculations.
