How to get the "goodness of fit" measure/s between two/or multiple models of mediation?
I'm conducting a mediation analysis (with 3 predictor, 1 mediator and 2 outcome variables), and I'm interested in getting the measure/s of "the goodness of fit" so I could compare models.
My professor mentioned that I could compare them by checking the "chi square for nested models" (If I understood him correctly), but I can't seem find that option in mediation analysis. Since I'm quite inexperienced, I'm interested about:
- How can I obtain the relevant measures?
- Which measures should be included and consulted as "the goodness of fit" parameters in that analysis/procedure, and;
- How do I report them?
Any information and suggestion would be highly appreciated.
Thanks in advance!
