Thank you for your reply and sorry for my ambiguity.
I computed:
summary(anova1 - aov(math ~ as.factor(schoolid), data=nels88))
ICC1(anova1)
ICC1 comes from the multilevel package. I have found an article where it
is pointed out that with this formula:
34.011/(34.011+72.256)
[1] 0.3200523

Hi everyone,
I need to get a between-component variance (e.g. random effects Anova), but
using lmer I don't get the same results (variance component) than using
random effects Anova. I am using a database of students, clustered on
schools
