Discrete Time Models for Some Statistical Problems
University of Zaragoza, Spain
In this communication, two different statistical problems are presented under a same paradigm. Two discrete time operators governing the evolution of two different statistical problems, one of them that models the random trading of a collectivity of free economic agents and another one that models the classical problem of an ideal gas. The equilibrium distributions for both problems are the Exponential wealth distribution for the economic system and the Gaussian velocity distribution for the ideal gas. The motivation and the derivation of these models that can be seen as a discrete time alternative or extensions of the continuous Boltzmann equation are explained.
