Hi.
I am a little bit confused here. I am running a univariate model including GxE interaction in it. As a result, I am getting that c path is very close to zero and I can omit it. However, its moderation is statistically significant and I have to keep it in the model. How would one interpret that?
On one hand, I understand that when we don't take a moderator into account (or M=0), we calculate paths for all persons in the data set despite their difference in the measured environment. And in this case, the c path on average might be zero, but it does change with different values of the moderator.
On the other hand, I am a bit worried about the model. How can moderation of a path be estimated if this path does not exist on the first place?
Anyone who can disentangle this for me, please? Thank you in advance.
