Spurious correlations

Avoid spurious correlations between measures with power-law dynamics by using a non-parametric test for assessing significance.

Usage

• main function: get_significance.m for obtaining a p-value by the surrogate data procedure.
• see run_example.m for how to run it.
• see plot_simulation_figures.m for recreating the simulation figures 2a), 2b) and 2c) from the paper.
