On adaptive wavelet estimation of a class of weighted densities
Weighted density density estimation plug-in approach wavelets block thresholding reliability series system parallel system.

We investigate the estimation of a weighted density taking the formg=w(F)f, where fdenotes an unknown density,Fthe associated distribution function andwis a known (non-negative) weight.Such a class en...
Skew-symmetric distributions and Fisher information -- a tale of two densities
singular Fisher information skew-normal distributions skew-symmetric distributions skewing function symmetric kernel

Skew-symmetric densities recently received much attention in the literature, giving rise to in-creasingly general families of univariate and multivariate skewed densities. Most of those families,howev...
Distances and Riemannian metrics for multivariate spectral densities
multivariate spectral densities Riemannian metrics

We first introduce a class of divergence measures between power spectral density matrices. These are derived by comparing the suitability of different models in the context of optimal prediction.
