Questions on the change of variance
Posted: Wed Feb 14, 2018 12:19 pm
Dear everyone:
I have a question on the drop of variance at the higher level. I am modeling 2 two-level random slope model. I found that when I just added some independent variables into the null model, and all slopes are fixed, but the variance at level-2 (school) still drops. I was a lit bit confuse about this drop. I can understand the drop of the variance at the individual level, but how does the drop at level-2 occur?
Thanks everyone!
