Hi,
I am working with Benin IR data to explore the factors associated with educational achievement (v106). My supervisor suggested that I check ICC value first since the data are clustered, and then choose between -logit- and -melogit- depending on whether the ICC is above the threshold of 0.15. Now it seems ICC can be calculated both before:
------------------------------------------------------------
. loneway v106, v021
Intraclass Asy.
correlation S.E. [95% Conf. Interval]
------------------------------------------------
0.25242 0.01320 0.22655 0.27829
------------------------------------------------------------
and after melogit:
------------------------------------------------------------
melogit v106, || v021:
esttat ICC
Level | ICC Std. Err. [95% Conf. Interval]
-----------------------------+------------------------------ ------------------
v021 | .3073749 .0158921 .2771332 .3393674
------------------------------------------------------------
As you can see, these two methods produce dissimilar results. Despite the necessity of using -melogit- being obvious, I'd like to know the right course of action to follow: before/after/both?
Thank you.
