Hello,
I am fitting a fixed factor model and the variance at level 2 is negative. Would any of you know what this means, and how I compute an ICC ? Shall I use the absolute value when computing it ? If so, this would underestimate the total variance : varL2negvalue / varL2neg_value + VarL1
Thank you ...
