CMB bispectrum, trispectrum, non-Gaussianity, and the Cramer-Rao bound
Minimum-variance estimators for the parameter fnl that quantifies local-model non-Gaussianity can be constructed from the cosmic microwave background (CMB) bispectrum (three-point function) and also from the trispectrum (four-point function). Some have suggested that a comparison between the estimates for the values of fnl from the bispectrum and trispectrum allow a consistency test for the mod...
متن کاملHeteroscedastic Sequences: Beyond Gaussianity
We address the problem of sequential prediction in the heteroscedastic setting, when both the signal and its variance are assumed to depend on explanatory variables. By applying regret minimization techniques, we devise an efficient online learning algorithm for the problem, without assuming that the error terms comply with a specific distribution. We show that our algorithm can be adjusted to ...

متن کاملAN ESTIMATE OF THE PRIMORDIAL NON-GAUSSIANITY PARAMETER fNL USING THE NEEDLET BISPECTRUM FROM WMAP
We use the full bispectrum of spherical needlets applied to the WMAP data of the cosmic microwave background as an estimator for the primordial non-Gaussianity parameter fNL. We use needlet scales up to lmax = 1000 and the KQ75 galactic cut and find fNL = 84 ± 40 corrected for point source bias. We also introduce a set of consistency tests to validate our results against the possible influence ...
متن کاملPrimordial Non-gaussianity, Scale-dependent Bias, and the Bispectrum of Galaxies
The three-point correlation function of cosmological fluctuations is a sensitive probe of the physics of inflation. We calculate the bispectrum, Bg(k1, k2, k3), Fourier transform of the three-point function of density peaks (e.g., galaxies), using the Matarrese-Lucchin-Bonometto formula. The bispectrum of peaks is not only sensitive to that of the underlying matter density fluctuations, but als...
