SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires powerlaw, numpy, scipy, networkx, mesa, pandas, matplotlib.

What problem does it solve?

This skill helps you rigorously analyze complex systems by fitting heavy-tailed distributions, quantifying long-range dependence, measuring fractal structure, and simulating emergent dynamics.

Core Features & Use Cases

  • Power-law fitting & testing: Estimate scaling exponents and statistically compare power-law fit versus alternatives (e.g., lognormal, exponential).
  • Time-series and structure complexity: Compute the Hurst exponent, sample entropy, and fractal dimension via box-counting.
  • Network and dynamical modeling: Estimate bond percolation thresholds and run agent-based models (Schelling segregation) using Mesa.
  • Information-theoretic analysis: Compute Shannon entropy, mutual information, joint entropy, and normalized mutual information to relate signals.
  • Use case: Given a citation network degree sequence and a time series of an evolving metric, use this skill to test whether connectivity is scale-free, quantify temporal persistence, and compare dependencies between two processes.

Quick Start

Ask your AI agent to analyze a degree sequence for power-law behavior, estimate Hurst exponent and sample entropy for a time series, and run a Schelling segregation simulation to quantify emergent ordering.

FAQPage Schema
How do I test if my data follows a power-law distribution?

You can test if your data follows a power-law distribution by estimating scaling exponents and statistically comparing the power-law fit against alternative distributions like lognormal or exponential.

How do I estimate the Hurst exponent and sample entropy for a time series?

You estimate the Hurst exponent and sample entropy for a time series by applying R/S-based long-range dependence estimation and information-theoretic calculations to quantify temporal persistence and complexity in your data.

Can I run agent-based modeling simulations using Mesa for complex systems?

Yes, you can run agent-based modeling simulations using Mesa to simulate emergent dynamics, such as executing Schelling segregation models to quantify emergent ordering within complex systems.

Does this approach support estimating bond percolation thresholds and fractal dimensions?

Yes, this approach supports estimating bond percolation thresholds using Monte Carlo methods and measuring fractal structure by computing fractal dimensions via box-counting estimation for spatial complexity.

How do I compute Shannon entropy and mutual information to compare signals?

You compute Shannon entropy and mutual information to compare signals by applying information-theoretic analysis, which calculates joint entropy and normalized mutual information to relate dependencies between processes.

What is the best way to analyze a citation network for scale-free connectivity?

The best way to analyze a citation network for scale-free connectivity is to test the degree sequence for power-law behavior to determine if the network connectivity exhibits heavy-tailed distribution scaling.
