Cosmological Non-Gaussian Signature Detection: Comparing Performance of Different Statistical Tests

<p/> <p>Currently, it appears that the best method for non-Gaussianity detection in the cosmic microwave background (CMB) consists in calculating the kurtosis of the wavelet coefficients. We know that wavelet-kurtosis outperforms other methods such as the bispectrum, the genus, ridgelet-...
