Hello,
Below are the two examples of rddensity plotting. As per my understandings, this test is used to checks the manipulation of running variable around the cutoff value in regression discontinuity design (RDD) analysis. If the p-value > 0.05, its means there is no systematic manipulation around cutoff (same like both below figures p-value fairly >0.05).
My question is that in 1st figure right side line is below than left, while in 2nd image right side line is above than left side line. To enhance my understandings, I want to knows that is these lines depicts something in rddensity plotting? and this left and right lines mismatch in both figures reflects something different interpretation of both figures(or just to show discontinuity) while p-value is insignificant in both cases., or P-value is enough to interpret rddencity plotting by ignoring left vs right lines difference?
Thanks
