Hi,
I have a question about moderation in regression. I have 21 interaction terms which have been entered in a regression and while the overall addition to the model is not significant, a couple of them are significant predictors. My question really is how to interpret this?
Logically I would enter each of them individually so that we can see if the addition of the significant ones adds to the model, but everything I've read enters all interactions in one block. As such, it should be interpreted as a non-significant addition but I don't want to loose the fact that some of the interactions are adding something. Ideally, a reference which says I can now just run the same analysis again but only entering the ones which came up significant in the first analysis would be ideal but I can't seem to find one.
Any help would be greatly appreciated!
Thanks
Josie
