Hi,
Let's assume that we have a HLM model with crossed effects (2 levels). Here is the model: mixed Y X || _all:R.Level1 || _all:R.Level2 . How should we write the code when we are intending to allow the slope of X to change across both Level1 and Level2???
I am tagging Clyde, since his comments have always been useful and timely.
