Abstract: The Diffeomorphism Kernel Density Estimator (DKDE) requires the estimation of an optimal value of the bandwidth to ensure a reliable pdf estimation of bounded distributions. In this paper, we suggest to approach the optimal bandwidth value by adapting Plug-in algorithm to DKDE estimator. We will show that the pro-posal method allows better density estimation in the MISE sense. Otherwise, the Gibbs phenomenon com-pletely disappears. These results are illustrated by some bounded and semi bounded distributions simulations.
