parameterization for partly nested design with repeated measurements
What Dr Bates means is, in case he's not here to answer himself, that (1|school/class) always means class nested in school but it's easy to confuse this notation and by mistake write (1|class/school) meaning school nested in class, which does not make sense andydolman at gmail.com

Dear Mr Bates Thanks ?very much for all your remarks.
"1|school/class" is the same as "1|school + 1|class", isn't it? If the classes have unique labels they are. ?Technically the expression (1 | school/year) expands to (1|school:class) + (1|school) but if the classes are labeled uniquely then (1|school:class) is the same as (1|class)
Do you mean that the notation (1|school/class) do not always read "class nested in school and, both class and school, as random effects" ? Regards, Marina
