Cover Story: Permutation entropy (PE) is a popular tool to analyze time series in order to either estimate the degree of randomness of a time series source or to detect changes in its dynamics. However, most works that rely on PE neglect the crucial problem of considering the statistical significance of a PE assessment, or, equivalently, of estimating its uncertainty—a task that is hardly feasible in most cases. A new, viable approach to carry out this estimation exploits the technique of surrogate data generation. Using the technique as a proxy generator of the source’s dynamics allows us to assess its statistical properties. View this paper
