In this comment we point out that this model can be considered as a particular realization of the general framework for the spectrum and statistics of the CMBR we proposed in astro-ph/9611208, based on the hypothesis of conformal invariance. The implication of this hypothesis is that density perturbations are nongaussian with a spectral index n > 1.1 page, Revtex fileAstrophysicsHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
