Calculating ICC1, ICC2, rwg PreviousNext

Dear Mplus experts,

I am calculating a twolevel model and for the final paper I would like to justify the aggregation of the individual level measures to team level measures, so I would like to compute ICC1, (including an F test), ICC2 and rwg for that purpose.

However, I am still new to Mplus and still have some questions in this regard:

1) When I run the null model (type = basic twolevel with no model specified) the output shows ICCs. Am I correct in assuming these are ICC1 values?
2) If so, how can I obtain the F statistic for ICC1?
3) How do I calculate ICC2?
4) How do I calcaulte rwg?

Any help would be much appreciated!
Thanks and best regards!

See our 2 FAQs:

Icc changes from one model to another

ICCs for 3-level

Mplus does not provide F-tests

Just to follow up on this thread, is there a way to test rwg in Mplus? I want to justify aggregation of the individual data to the group level and thus want to calculate rwg but can't seem to find any discussion related to this topic.

Thank you.
