Hi,
 I am currently running the following negative binomial GLM:

glm89.nb <- glm.nb(AvGUD ~ Year*Trt*Micro + (0 + Micro/Trt/Year))

where Year has 3 levels, Trt has 2 levels, and Micro has 3 levels.

>From what I have read the above model has a 3 way interaction
(Year*Trt*Micro), and Micro is nest within Trt and Trt is nested with Year
(0 + Micro/Trt/Year).
I was hoping someone could confirm that this is actually what the model is
running?

Thank you very much for your time,
Rebecca
