Abstract
The Pareto distribution, whereby at large enough x the probability density ρ(x) ∼ x − α (α ≥ 2), is quite important in both basic and practical aspects. The main point is its essential difference from the normal (Gaussian) distribution; namely, the probability of large deviations in this case proves to be much higher. Universal applicability of the normal distribution law remains a common belief despite the lack of objective proof in many applied areas. Here we consider how a Pareto distribution arises in a dynamic system exposed in a noise field, and discuss simplest unidimensional models where the system response in a broad range of the variable can be accurately enough approximated with such a distribution.
