Hello,

I have the following design, counts were collected at different transects,
different depths and different sites at different times. Time is continuous
and assumed to be random, all the others are categorical fixed where
transect is nested within depth which is nested within site.

I would like an expert opinion about the following code where intercept is
modeled as random (I am not sure if this is the right way).

a<-factor(transect)
b<-factor(depth)
c<-factor(site)
g<-lmer(count~(1|time)+(time|a:b:c), family="poisson")

Thanks,
Y
