I am doing a regression discontinuity analysis in R (using the rdd package) and I am interested in testing a moderation hypothesis. I think that the effect of the treatment will depend on a third variable. Is this even a sensible analysis? There doesn't seem to be anything about moderation in the regression discontinuity design resources that I have found. Thus, I'm wondering if that's not a common analysis.
