Hi, can anyone tell me how to nest two fixed factors using glmer in lme4? I
have a split-plot design with two fixed factors - A (whole plot factor) and B
(subplot factor), both with two levels. I want to do GLMM as I also want to
include different plots as a random factor. But I am interested on the effect
of A a B and their interaction on the response variable. I tried
this:glmer(response~A*B+(A/B)+(1|C),data=Exp2,family=poisson but it gives the
same output as if I removed (A/B) all together or used (A:B) instead thus the
output is the same as: glmer(response~A*B+(1|C),data=Exp2,family=poisson anyone
can help with how I define this nesting, so that data are analysed correctly
given my split-plot design? thanks, Martina
