I know that fractal structures have power-laws in various forms "hidden" in them. I am looking for the most simple fractal model that I can find that generates time series with, say, Pareto-distributed increments. Or any other heavier-than-Gaussian -tailed distribution.

By generating time series, I mean that the system can be described by some kind of observations, any type. Temperature, some integral measure, derivative of some property, etc. For example, consider a system of agents organized in a network model, and define a sort of interaction between them on a graph. The observed measure of biggest cluster, or sum of vertex weights, or number of vertices with weight bigger than some specific number, etc., iterative, could be a time series.

By fractal properties I mean property of self-similarity. For example, having structure (for an agent-based model that could be graph structure of connectivities) that is defined by the same rule on all scales. For the mentioned exmaple of graph structure, that would be structure among clusters that copies structure of nodes inside every single cluster.

I am trying to come up with the most simple system that has fractal properties, demonstrates non-normality of the whole while having normality or binary behavior at the lowest level, and has clear connection between the two. Any help would be much appreciated!

    $\begingroup$ This question is lacking context - what exactly do you mean by a "fractal model", and how would it "generate time series"? $\endgroup$

1 Answer 1


your answer is hidden in the self organized criticality (SOC) concept. there is many model that have applied in many branch of science that obey SOC.

this concept for the first time was introduced by Bak et al with "Abelian Sand pile model".

this model is the simplest model can receive to critical state (showing power law and infinite temporal-spatial correlation) without any control parameter.

here you can find many things about this concept. even the simulation code of the model.
