Thank you for your reply. VARCOMP is available at SPSS advanced models, I'm not sure for how long it exists... I only work with SPSS for the last 4 years... My model only has crossed random effects, what perhaps would drive me to lmer(). However, as I have unbalanced data (why it is normally

I used SPSS over 25 years ago, but I don't recall ever fitting a variance components model with it. Are all your random effects nested? If they were, I would recommend you use 'lme' in the 'nlme' package. However, if you have crossed random effects, I suggest you try 'lmer' associated

Re: [R] Variance components from lm?

2005-07-15 Thread Prof Brian Ripley
In any case, the question was about lm, not lme. The short answer is that this is easiest from aov, a wrapper for lm, and for balanced data will be equivalent to as using lme. Steve can find worked examples for interlaboratory data in MASS (the book, see the FAQ). On Thu, 14 Jul 2005, Spencer

[R] Variance components from lm?

2005-07-14 Thread Steve Ellison
I often use simple nested random-effect models for interlaboratory data. The variance components are important things to know. Is there an R function or package that gets variance components from lm objects? Or can someone point me to a method of doing so?

Under normal circumstances, 'RSiteSearch(variance components)' would likely identify lme in package nlme and lmer in package lme4. I recommend lme, as it comes with a fairly complete set of helper functions described in Pinheiro and Bates (2000) Mixed-Effect Models in S and S-Plus

lme in library(nlme) is vastly superior in many ways to varcomp, but has the disadvantage of being difficult to use, at least in my experience. When I need it, I also refer to José C. Pinheiro and Douglas M. Bates (2000) Mixed-effects models in S and S-PLUS (NY: New York : Springer). I
