Dear Maarten,
Thank you for responding to the post. I think I will just stick with my original codes for margins.
I have a rather long list of controls and even when I take those out, using your tip produces too much collinearity and most of the model is dropped. I think this is because I am including all lower order interactions in addition to the higher order interactions.
Best,
