How to calculate Intraclass-coefficient in 2-level Linear Mixed-Effects models?
Dear R-users,
consider a 2-level linear mixed effects model (LME) with random intercept
AND random slope for level 1 AND 2. Does anybody know how to calculate
Intraclass-coefficient (ICC) for highest (innermost) level 2 ??? In the
literature, I did not find an example for these kind of komplex models.
For 1-level Random-Intercept models it would be easy:
ICC = variance due to the clustering variable / (variance due to the
clustering variable + variance remaining) = sigma^2_RandomIntercept /
(sigma^2_RIntercept + sigma^2_error)
My data are similar to Pixel-Data from R-package nlme:

Very basic statistics in R
...f x -> ?
- the uncertainty on the standard deviation -> ?
Anyone has an idea?
Thanks in advance,
regards,
Xavier

An ANOVA test that uses a distance matrix like hierarchical cluster analysis?
...rences. Is there a ANOVA style of analysis that makes use of distance
matrices?
Any thoughts would be appreciated as statistics is not my specialty although
I am happy with programming in R, Matlab etc...

FW: error predicting values from the LME
HI all,
I might add some more information in order to possibly solve my problem. I'm
really stuck and no obvious solutions do the trick.
I'm using R 1.7.1 on Windows 2000 with the packages regurarly updated.
I'm using hypothetical data constructed as a pseudo population conforming to
a certain Var-Cov structure.
I might add that just
> predict(level2)
works. But when I add the
