I have used the postestimation command "estat icc" to estimate intracorrelation coefficients after two multilevel models (command "mixed", random effects at one level; ~10k observations each). I am now looking to interpret my results (.133 in one case, .182 in another). Would you consider these results high or low when it comes to an ICC?

My ultimate goal is to determine whether a multilevel approach is necessary, or whether I should use GEE instead.

Many thanks!
