#' Amount of regularization/penalization
#'
#' A numeric parameter function representing the amount of penalties (e.g. L1,
#' L2, etc) in regularized models.
#'
#' @inheritParams Laplace
#'
#' @details
#' This parameter is used for regularized or penalized models such as
#' `parsnip::linear_reg()`, `parsnip::logistic_reg()`, and others.
#' @examples
#' penalty()
#' @export
