I have a moderated mediation model with a multicategorical IV (4 groups) and I know that Hayes' Process Macro runs regressions so I have to test for assumptions.
- This is done by testing all paths as seperate models in SPSS, correct? (Path a from X to Med, Path b from Med to Y, Path c from X to Y)
But with Categorical IV, usually ANOVA is performed so I am unsure how to test for regression assumptions.
- Do I test for ANOVA assumptions for Path a and Path c, because the predictor is nominal?
I am thankful for everyone who is willing to help - Thank you so much!
