Type I or III SS with mixed model function lme
...- lme(fixed=Y~A+B+A:B, random=~1|Site). Y is a
continuous variable while A and B are factors. The data set is balanced
with the same number of observations in each combination of A and B. There
are two hierarchical levels: Site and plots nested in site.
He tried two different ways of getting theANOVA table: anova(out) and
anova(out, type=”marginal”).
Since the data were balanced, these two ways should (I think) give the same
output since they correspond to Type I and III sums of squares in the SAS
terminology. At least, this is the case with normal (i.e. not mixed) linear
models. However,...
