Hello,
I need to fit a "Nested Random Effects ANOVA model" with the lmer function in the lme4 package. I read through the documentation http://lme4.r-forge.r-project.org/book/Ch2.pdf and the data structure of the "Pastes" data set looks almost exactly like mine. The only difference is that I have another factor which distinguishes controls from diseased patients. For the "Pastes" data set they fittet their "Nested Random Effects model" as follows: lmer(strength ~ 1 + (1|sample) + (1|batch), Pastes, REML=FALSE) My data strucute looks like as follows: http://www.pic-upload.de/view-12130948/data.png.html I am not sure of how to fit my model now. Would it be as simple as only adding the third factor? lmer(Protein_1 ~ 1 + (1|Group) + (1|Sub_Disease) + (1|Disease)) ?
