The emergence of the seeds of cosmic structure from a perfect isotropic and homogeneous Universe has not been clearly explained by the standard version of inflationary models. We consider alternative scenarios were the emergence of an anisotropic and inhomogeneous Universe from an initial isotropic and homogeneous state can be explained by the introduction of the "self-induced collapse hypothesis" of the inflaton wave function. Our aim is to test these models through statistical analysis comparing them with recent data of the Cosmic Microwave Background and galaxies surveys. This procedure will restrict the value of free parameters and analyze the viability of each scheme within results of latest observational experiments.
