Hello everyone,

In this model:

strctr.all <- glmmadmb(pellets ~ season * (totl.splgs + totl.trees +
                                       pctMidCov + lc +
                                       cc + BAsplgs + BAtrees) +
                                       offset(ln.days)+(1|plot/stand)+
(1|year),
                                       data=hv, family="nbinom")

Is (1|plot/stand) correct to mean group=stand ?

Is the repeated measurement correctly addressed with (1|year) ?

There are 3 repeated measures of summer (2010,2011,2012); 3 of winter
(years 2011,2012,2013) but the 3 measures per season are a "nuisance"
source of random variation.   The Season variable Is the fixed variable of
interest.

Data structure: 2,184 plot records of pellet counts - the response variable.
In 26 forest stands were subsampled with 20 summer and 10 winter
Plots/stand for vegetation metrics. Stands are replicates.

Thanks much,
Sheryn
