WitrynaRob Hyndman provided an excellent answer that recommends the Sheather-Jones method. One addition point. In R, for the density function, you set the bandwidth explicitly via the bw argument. However, I often find that the adjust argument is more helpful. The adjust argument scales the value of the bandwidth.
