However, like traditional single scale nonlinear dynamicparameters ApEn and SampEn, PE detects the dynamicchanges and randomness of time series only in a single scale.Recently, multiscale permutation entropy (MPE) was introduced by Aziz and Arif in the literature [13] to measure thecomplexity of time series in different scales and is comparedwith MSE through analyzing the physiological time seriesand the results show that MPE is more robust than MSE inanalyzing the presence of artifacts and white Gaussian noise
