Hi all
I am working on a research questions to see the effects of district
level variables on asthma. I am using individual level (level1)
variables are district level variables (level 2). I am using
individual level variables as control.
1) My question is do I need a random slop model in this case? or
random intercept models are appropriate.
2) If yes, then how to decide which individual level variables should
be used for random slop?
