Doubts about mixed effect models
...answers about how to construct the model.
The first suggestion was to treat year as a fixed rather than a random
effect because it won't be practical to estimate the variance of a
random effect
with only four levels. So, I constructed the model like cited below:
m1<-lmer(riqueza~área*ano+isolamento*ano(1|fragmento),family=poisson
The second suggestion proposed to treat year as a random effect, as cited
bellow:
m1<-lmer(riqueza~área*ano+isolamento*ano(ano|fragmento),family=poisson
And the third suggestion also proposed to treat year as a random effect,
but to consider it *as continuous...
