I have been trying to find a way to compare two coefficients from two different nonparametric rd models.
Using rd command (by Austin Nichols), I have run one rd model to two different samples separately.
Now, I want to compare if the estimate of the regression discontinuity is the same between the two samples.
Is there anything like suest for the rd commands or in general nonparametric regressions?

Any advice would be appreciated!

Thanks,
Nami
