Description

Jupyter notebook for nonlinear time series analysis of the palaeoclimate proxy records used in the paper. It calculates the number of potential wells, the entropy of the data, the order pattern (permutation) entropy, the recurrence quantification/network measures, DET, LAM, transitivity, and average path length as well as the visibility graph based irreversibility test statsitics p(k) and p(C).

The repository also contains the data sets used in the analysis in the folder Data.
