In rdhte: Heterogeneous Treatment Effects in Regression Discontinuity Designs

#' @title rdhte: RD Heterogeneous Treatment Effects Estimation and Inference
#'
#' @description Building on the recent developments in Calonico, Cattaneo, Farrell, Palomba, and Titiunik (2025), this package implements
#'  estimation and inference of heterogeneous treatment effects in RD designs.
#'  The package includes two main commands: \code{\link{rdhte}} conduct estimation and robust bias-corrected inference for conditional RD treatment effects,
#'  for a given choice of bandwidth parameter; and \code{\link{rdbwhte}} implements automatic bandwidth selection methods.
#'  We illustrate the methods implemented in the package \code{\link{rdhte}} using a canonical empirical application.
#'  We also demonstrate how the package \code{\link{rdhte}} complements, and in very specific cases recovers,
#'  the methods available in the packages rdrobust (Calonico, Cattaneo, Farrell, Titiunik (2017) and rdmulti, Cattaneo, Titiunik, VazquezBare (2020).
#'
#' Commands: \code{\link{rdhte}} for estimation and inference.
#'   \code{\link{rdbwhte}} for data-driven bandwidth selection.
