May 14 at 17:45 | comment | added | user9011032 | Did I rule out that my mediator is a confounder by the mediation analysis I did? Or is there any statistical test I could do, to find that out? | |
May 11 at 15:15 | comment | added | Peter Flom | But OP did do mediation analysis, which should deal with this. | |
May 11 at 15:07 | comment | added | Peter Flom | Yeah, I think you are right. But it can be tricky to distinguish confounder and mediator. Usually, people say a mediator has to be on the causal path. | |
May 11 at 14:34 | comment | added | BenP | But could that not be the case too for a confounder, so that the uncontrolled effect of X is at least in part spurious? | |
May 11 at 14:31 | comment | added | Peter Flom | It's mediation because the effect of the IV changed a lot when the mediator was added. | |
May 11 at 14:26 | comment | added | BenP | Yes correct @PeterFlom, sorry! But on the other hand, maybe you could give me an answer as well. I mean, since we do not know the exact meaning of the variables involved, you must have had a reason to call it "mediation" based on the analyses done. | |
May 11 at 14:24 | comment | added | Peter Flom | @BenP You put this as a comment on my answer, I think you meant it as a comment on the question | |
May 11 at 13:58 | comment | added | BenP | More a question than an answer: is it impossible for some reason, or unlikely, given all the results, that the CV variable is not a mediator but a confounder? If you cannot imagine why or how there would be mediation, why do you seem to rule out confounding? | |
