Power Fluctuations in the Wavelet Space: Large-Scale CMB Non-Gaussian   Statistics
  We analyse the large-scale coherence of the CMB anisotropy field with non-gaussian initial conditions usind 2-point function of the power fluctuations in the wavelet space. Employing the multivariate Edgeworth expansion (MEE) we constrain the normalization for the cosmic string mass-per-unit-lenght. The obtained value is consistent with the results obtained from the simulations of the evolution of the string network and by other large scale studies.
