Flexible covariate adjustments in RDD

Sharp Design

The simulations are based on the make_simple_rdd_data-DGP with \(1000\) observations. The simulation considers data under a sharp regression discontinuity design.

Fuzzy Design

The simulations are based on the make_simple_rdd_data-DGP with \(2000\) observations. The simulation considers data under a fuzzy regression discontinuity design.
