Silvio Queiros: Burr-class probability density functions from superstatistical dynamical processes
Abstract:
The concept of superstatistics has been introduced as a suitable approach to the analysis of driven complex nonequilibrium systems of several natures. In this talk I present a set of stochastic differential processes enclosed within the Feller class, which modified according to superstatistical requirements, lead to Burr-class probability density functions like the F-distribution or generalised Weibull-distribution. The usefulness of such an approach is depicted from examples of distributions obtained in financial markets and metaequilibrium Hamiltonian systems.
