Fluctuation and Noise LettersIn this paper, we propose multivariate multiscale weighted dispersion transfer entropy (MM-WDTE). This method introduces weight coefficients and weight probabilities in the symbolization process of dispersion patterns to retain key information to the greatest extent and effectively improve the robustness to noise.
