Abstract

We discuss a practical method to determine the eigenvalue spectrum of the empirical correlation matrix. The method is based on analysis of behavior of a conformal map at a critical horizon which is defined as a border line of the physical Riemann sheet of this map. The map is a convenient representation of the Marcenko-Pastur equation.
