#' rdmulti: analysis of RD Designs with multiple cutoffs or scores
#'
#' The regression discontinuity (RD) design is a popular quasi-experimental design
#' for causal inference and policy evaluation. The \code{'rdmulti'} package provides tools
#' to analyze RD designs with multiple cutoffs or scores: \code{\link{rdmc}()} estimates
#' pooled and cutoff-specific effects in multi-cutoff designs, \code{\link{rdmcplot}()}
#' draws RD plots for multi-cutoff RD designs and \code{\link{rdms}()} estimates effects in
#' cumulative cutoffs or multi-score designs. For more details, and related \code{Stata} and
#' \code{R} packages useful for analysis of RD designs, visit \url{https://rdpackages.github.io/}.
