In the article by Justin McCrary "Manipulation of the running variable in the regression discontinuity design: A density test" (2008) he estimates log discontinuity in the density of democratic vote share.
He finds a 52% discontinuity but does not elaborate on how to interpret this 52%. Intuition might imply a 52% drop in the density but it seems unlikely graphically and very possible that this value could exceed 100%

- Is it an arbitrary output best used for comparisons?
- What would a value over 100% mean?
