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!
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.
