Description
Summary:	•Consecutive m-histories of a time-series are mapped onto a finite set of elements.•The permutation entropy is used to detect dependencies.•Modified permutation entropy is used to detect determinism.•A regression based test is analyzed. In a recent paper Matilla-García and Marín (2010) propose a novel test to determine whether the dynamics of a time series are generated by a deterministic or a stochastic process. The results presented in the paper need some clarifications.
