I need to fit a "Nested Random Effects ANOVA model" with the lmer function
in the lme4 package.
I read through the documentation
and the data structure of the "Pastes" data set looks almost
exactly like mine. The only difference is that I have another factor which
from diseased patients.
For the "Pastes" data set they fittet their "Nested Random Effects model" as
lmer(strength ~ 1 + (1|sample) + (1|batch), Pastes, REML=FALSE)
My data strucute looks like as follows:
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)) ?
