Erratum to: Testing pattern synchronization in coupled systems through different entropy-based measures

Owing to a clerical error, the distance between two vectors was defined incorrectly for multivariate multiscale sample entropy (MMSE) in Table 1. The results and conclusion of our simulation was, however, unaffected because our simulation applied the correct definition, which is given below. For clarity, we give below the whole description of MMSE as in Table 1. The place where the mistake came in is shown in bold. We apologize for this oversight and for any confusion that it has caused.
