Hello dear STATList users
I hope all of you are doing great. This is the second time I post here.
For my thesis I’m testing two types of relationships:
1-The impact of groups of IVs on the DV, for this I used two-step difference GMM and its done.
2- The impact of moderator in moderating the relationship between certain IVs and the DV. Here is where I got confused and stuck.
I have tried ols for the moderator and I got the results, but, I’m not sure if I must use (two-step difference GMM) for moderator since I already used it (GMM) for the previous analysis for testing the effect IVs on the DV. I have tried so many times to run (two-step difference GMM) for the moderator but it keeps giving me error, I don’t know how to do it.
My question is: Do I have to use the (two-step difference GMM) for moderator analysis? Or is ols result enough?
Your help and advice are strongly appreciated.
Best regards
