Vielen Dank, Spencer. I could not find a published example where both the original data and conditional posterior variances were available. Instead, I toyed around a little with artificial data, and the (pretty pathetic) result below is the closest I came to "Monte Carlo-ing". I'm afraid I lack

I shall provide herewith an example of what I believe is "the conditional posterior variance of a random effect". I hope someone more knowledgeable will check this and provide a correction if it's not correct. I say this in part because my simple rationality check (below) didn't mat

[R] bVar slot of lmer objects and standard errors

2005-12-22 Thread Ulrich Keller
Hello, I am looking for a way to obtain standard errors for emprirical Bayes estimates of a model fitted with lmer (like the ones plotted on page 14 of the document available at http://www.eric.ed.gov/ERICDocs/data/ericdocs2/content_storage_01/000b/80/2b/b3/94.pdf). Harold Doran mentioned
