On The Dependence Structure of Wavelet Coefficients for Spherical Random Fields (2008)
Lan, Xiaohong, Marinucci, Domenico
We consider the correlation structure of the random coefficients for a wide class of wavelet systems on the sphere which was recently introduced in the literature. We provide necessary and sufficient...
The needlets bispectrum (2008)
Lan, Xiaohong, Marinucci, Domenico
The purpose of this paper is to join two different threads of the recent literature on random fields on the sphere, namely the statistical analysis of higher order angular power spectra on one hand,...
