Dear Statalist Community,
I have a somewhat silly question, but I hope you can help me clarify it. When running a Regression Discontinuity (or any other model, actually), I am clustering my standard errors by the population of the place of the interview to avoid within-group correlation:
However, my question is: do I also have to add my clustering variable as a covariate? Why/why not?
Thank you very much!
Best,
Cat

Code:

Thank you very much!
