Help: linear regression using modetator & control variables

[Jesse Nooijen]

Hey,

I'm currently trying to run a regression that uses both a moderator variable as well as several control variables. I just can't figure out how to properly run the regression.

Independent variable: Internationalization
Dependent variable: ROA
Moderator variable: R&D Intensity
Control variables: parentsize exportintensity exchangerate

Currently trying to run ''regress ROA Internationalization parentsize exportintensity exchangerate, vce(robust)'' as a test, as I do not understand the placement of the moderator variable. This currently delivers 0 observations...

If I need to post more information, please let me know.


Thanks in advance,
Jesse Nooijen

Please read the FAQ for the information you need to post. I can't work with text, I need a dataset and code. I presume you're doing this to do some mediation analysis?
