Zero inflated negative binomial
Hi all,
I am running the following model:
> glm89.nb <- glm.nb(AvGUD ~ Year*Trt*Micro)
where Year has 3 levels, Trt has 2 levels and Micro has 3 levels.
However when I run it has a zero inflated negative binomial (as I have lots
of zeros) I get the below error message:
> Zinb <- zeroinfl(AvGUD ~ Year*Trt*Micro |1, data = AvGUD89, dist...

Correct nested design for GLM
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 wa...
