# Generator token: 10BE3573-1514-4C36-9D1C-5A225CD40393

#' fits a kernel density estimate and calculates the effective degrees of
#' freedom.
#' @param x vector of observations; categorical data must be converted to
#'   non-negative integers.
#' @param xmin lower bound for the support of the density, `NaN` means no
#'   boundary.
#' @param xmax upper bound for the support of the density, `NaN` means no
#'   boundary.
#' @param type variable type; must be one of {c, cont, continuous} for
#'   continuous variables, one of {d, disc, discrete} for discrete integer
#'   variables, or one of {zi, zinfl, zero-inflated} for zero-inflated
#'   variables.
#' @param bandwidth the bandwidth parameter.
#' @param mult positive bandwidth multiplier; the actual bandwidth used is
#'   bw*mult.
#' @param degree order of the local polynomial.
#' @return `An Rcpp::List` containing the fitted density values on a grid and
#'   additional information.
