Hellinger-Bhattacharyya cross-validation for shape-preserving multivariate wavelet thresholding
Carlos Aya-Moreno, Gery Geenens, Spiridon Penev
The benefits of the wavelet approach for density estimation are well established in the literature, especially when the density to estimate is irregular or heterogeneous in smoothn…

Shape-preserving wavelet-based multivariate density estimation
Carlos Aya Moreno, Gery Geenens, Spiridon Penev
Wavelet estimators for a probability density f enjoy many good properties, however they are not "shape-preserving" in the sense that the final estimate may not be non-negative or i…
