Hello, I asked this question a little while ago ( https://stat.ethz.ch/pipermail/r-help/2008-April/158761.html ) but got no response. Can anybody explain to me the difference between /, :, and %in% in the definition of random effects in lmer, such as: (1|A/B), (1|A:B), (1|B %in% A)?
My understanding is that (1|A/B) is the same as (1|A) + (1|A:B), but I have not seen this stated explicitly anywhere. And I don't understand why (1|A/B) seems to be different from (1|A) + (1|B %in% A), isn't that what %in% means?
