#' Parameters for class-imbalance sampling
#'
#' For up- and down-sampling methods, these parameters control how much data are
#' added or removed from the training set.
#'
#' @inheritParams Laplace
#' @details
#' See `recipes::step_upsample()` and `recipes::step_downsample()` for the
#' interpretation of these parameters.
#' @examples
#' under_ratio()
#' over_ratio()
#' @export
