It has been shown that spectral statistics techniques, based on random matrix theory, can be applied to study correlations at ground level between the secondary particles of simulated extensive air showers. The statistical description of shower fronts provided by appropriate spectral measures makes it possible to separate them into different classes depending on the type of the primary cosmic ray. Using a suitable combination of spectral statistics in the framework of discriminant analysis, we introduce a new statistic which separates shower fronts according to the primary type with improved efficiency.
