The link I refer to: http://www.bristol.ac.uk/cmm/learning/multilevel-models/samples.html These hints, however, only relate to level 2 units ...

Good day Chris, thanks for your response. Yes, I can confirm that I added the denominator into the red nj. I used a cons (=1) vector. Regarding the level identifiers: When I specified case-id (1,2,3, etc.) and measurement occasion (e.g. 1,1,1) I get the error message in the attachment. However, when...
