lddtest

Perform equivalence testing for regression discontinuity designs (RDD) in Python.

This package implements three methodologies:

1. The classic manipulation test proposed by McCrary (2008): tested against DCdensity implemented in the R package rdd
2. The equivalence testing framework proposed by Hartman (2021): tested against the R functions rdd_equivalence
3. The logarithmic density discontinuity (LDD) test proposed by Fitzgerald (2024): tested against the R package eqtesting
