I am currently trying to run a multi-groups (2 groups) path analysis, where the predictor and outcome variables are both continuous, and the mediator is a three category ordinal variable.
I was wondering how best to input my mediator, in particular whether I should list this in the input as a categorical variable? I understand that if a categorical variable has less than 5 categories it should not be treated as continuous, but I wondered whether that is the same if treating the variable as a mediator?
I have your book, and have been reading the section on binary and ordinal variables. I donít think the input provided in 8.26 is appropriate in my situation as the outcome variable in the example is categorical and mine is continuous, is that correct?
Iíd very much appreciate any guidance, Best wishes, Nathalie
Many thanks, that is very helpful. If I can just clarify one point, my mediator does indeed have a larger proportion of participants in the lowest category. Are the methods in table 8.29 more appropriate in this situation?
