Study demonstrates a new recurrence-based method that mimics Kolmogorov-Smirnov test

The recurrence plot is a vital tool for analyzing nonlinear dynamic systems, especially systems involving empirically observed time series data. RPs show patterns in a phase space system and indicate where data visit the same coordinates. RPs can also mimic some types of inferential statistics and linear analyses, such as spectral analysis. A new paper in the journal Chaos, provides a proof of concept for using RPs to mimic the Kolmogorov-Smirnov test, which scientists use to determine if two da...
