Correlation function and generalized master equation of arbitrary age
Paolo Allegrini, Gerardo Aquino, Paolo Grigolini +3
We study a two-state statistical process with a non-Poisson distribution of sojourn times. In accordance with earlier work, we find that this process is characterized by aging and…
Non-Poisson processes: regression to equilibrium versus equilibrium correlation functions
P. Allegrini, P. Grigolini, L. Palatella +2
We study the response to perturbation of non-Poisson dichotomous fluctuations that generate super-diffusion. We adopt the Liouville perspective and with it a quantum-like approach…
Multi-Scaling Comparative Analysis of Time Series and a Discussion on "Earthquake Conversations" in California
Nicola Scafetta, Bruce J. West
Time series are characterized by complex memory and/or distribution patterns. In this letter we show that models obeying to different statistics may equally reproduce some pattern…
Aging and Rejuvenation with Fractional Derivatives
Gerardo Aquino, Mauro Bologna, Paolo Grigolini +1
We discuss a dynamic procedure that makes the fractional derivatives emerge in the time asymptotic limit of non-Poisson processes. We find that two-state fluctuations, with an inve…
Non-Poisson dichotomous noise: higher-order correlation functions and aging
P. Allegrini, P. Grigolini, L. Palatella +1
We study a two-state symmetric noise, with a given waiting time distribution , and focus our attention on the connection between the four-time and the two-time correlation fu…
Multiresolution Diffusion Entropy Analysis of time series: an application to births to teenagers in Texas
Nicola Scafetta, Bruce J. West
The multiresolution diffusion entropy analysis is used to evaluate the stochastic information left in a time series after systematic removal of certain non-stationarities. This met…
