I conducted an ACBC and analyzed attribute interactions with the 2LL Likelihood test. Three significant interactions were found and in the export I can also see the chart with the additional part worths for each two-way combination of attribute levels.
My question is, how can I see, which levels interact significantly?
So the 2LL test tells me, that there is at least one two-way group with significant different utilities, or am I missinterpreting the result?
Is there something like a post-hoc test module to investigate which two-way interactions are significant and which are not?
THANK YOU very much for your help.
