The present work is an application of linear and non-linear tools, with particular attention to the chaotic dynamics, in order to analyze the daily visits to the Italian newspaper website “La Repubblica”. The series is examined, using the time chart, the recurrence plot and the power spectrum. In the phase space, the detrend series consists of 5 clusters of points, explained by the frequency distribution that is centred on 3 values. The analysis is performed by calculating the embedding dimension, Lyapunov exponents and the correlation dimension that suggests the existence of an attractor. A non-linear forecast of the following values is made. In conclusion, some theoretical issues on the characteristics of a chaotic system emerge.

Abstract
The present work is an application of linear and non-linear tools, with particular attention to the chaotic dynamics, in order to analyze the daily visits to the Italian newspaper website “La Repubblica”. The series is examined, using the time chart, the recurrence plot and the power spectrum. In the phase space, the detrend series consists of 5 clusters of points, explained by the frequency distribution that is centred on 3 values. The analysis is performed by calculating the embedding dimension, Lyapunov exponents and the correlation dimension that suggests the existence of an attractor. A non-linear forecast of the following values is made. In conclusion, some theoretical issues on the characteristics of a chaotic system emerge.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
