NEXT: Stata module to perform regression discontinuity

This program, which is designed to estimate a local average treatment effect in the context of a strict regression discontinuity design, uses a data-driven algorithm that simultaneously selects the polynomial specification and bandwidth combination that minimizes the predicted mean squared error at the threshold of a discontinuity. It achieves this selection by evaluating the combinations of specification and bandwidth that perform best in estimating the next point in the observed sequence on each side of the discontinuity.
