Regression Discontinuity

Regression Discontinuity is a quasi-experimental impact evaluation design which attempts to find the causal effects of interventions by assigning a threshold above and below which the treatment is assigned. Observations closely on either side of the threshold are compared to estimate the average treatment effect.

Types of RD

Sharp RD

Sharp regression discontinuity designs are designs where the cut off point perfect predicts whether the subject(individual, groups, etc) becomes treatment or control.
