rddsga allows to conduct a binary subgroup analysis in RDD settings based on inverse propensity score weights (IPSW). Observations in each subgroup are weighted by the inverse of their conditional probabilities to belong to that subgroup, given a set of covariates. Analyzing the differential treatment effect in the reweighted sample helps isolating the difference due to the subgroup characteristic of interest from other observable dimensions.
