[R-sig-ME] intra and inter-observer correlations in a bivariate model

Dear All,

Perhaps the answer to my question is trivial, but I got stuck in my own arguments and hope someone can drag me out

Here is the problem ... we have two behavioral traits (say A and B) which are measured for a range of individuals in different years. We have calculated within- and between-year reliabilities on the basis of the basis of residual, individual and year:individual variance components. Next what we want to study is to what extent the correlations between A and B differ if considered within or between years. It is a test-retest type of question as for the reliabilities, but now between the two traits, and cannot clear my mind on how to get those...

any help would be greatly appreciated
