mixing nested and crossed factors using lme
...Blocked(list(pdIdent(~sitenumber-1), pdIdent(~rater-1)))),data=scores)
which makes sense, and I then calculated the intraclass correlation using the within sitenumber (ie among raters) variance, the within rater variance and the residual variance (using VarCorr(fit)):
rho = var_among/(var_among + var_within + var_resid)
Now, the raters can be divided into two groups. I would like to include group as a fixed factor, to test whether there is a difference in scores between groups (I know the number of raters is too small. This is a pilot study and I am really just trying to get the analysis right in cas...
