On the Genuine Relevance of the Data-Driven Signal Decomposition-Based Multiscale Permutation Entropy. [PDF]
Ordinal pattern-based approaches have great potential to capture intrinsic structures of dynamical systems, and therefore, they continue to be developed in various research fields. Among these, the permutation entropy (PE), defined as the Shannon entropy of ordinal probabilities, is an attractive time series complexity measure.

On the Statistical Properties of Multiscale Permutation Entropy: Characterization of the Estimator's Variance. [PDF]
Permutation Entropy (PE) and Multiscale Permutation Entropy (MPE) have been extensively used in the analysis of time series searching for regularities. Although PE has been explored and characterized, there is still a lack of theoretical background regarding MPE. Therefore, we expand the available MPE theory by developing an explicit expression for the
