摘要：
Complexity is an important feature of complex time series. This paper proposes a new entropy plane using past Tsallis entropy and past R e ' nyi entropy by weighted permutation pattern (PTEWP and PREWP), to quantify the complexity of time series. Through simulated data and actual data, we have verified the effectiveness of the entropy plane method. The results show that the new entropy plane can be used as an effective tool to distinguish financial markets. (c) 2021 Elsevier Ltd. All rights reserved.
