GLMM random effects
...reatment, Session, Total biomass, and/or %Edible food for the fixed
effects. (Colony, Plot, Treatment, and Session are all factor variables).
And an example of the R code that we started with is:
PDmodel_1 <- lmer(Density~1+Treatment+Session+Biomass+(1|Colony/Plot),
family=quasipoisson, data=DensityPD)
My main question is:
Does this accurately take into account our nested and repeated measures
design? Have we accounted for any possible pseudoreplication with this type
of analysis? Do I need to also look at type AR-1 error structures (or can I
do that in a glmm?) Or is there a simpler way you...
