This command attempts to correlate ts1.csv and ts2.csv over a time range of +/- 100 days with a bin width of 1.5 day. Try it, see that peak at 42 days? It should be noted that unlike a traditional cross correla
Paper:Crossformer: Transformer Utilizing Cross-Dimension Dependency for Multivariate Time Series Forecasting Code: github.com/Thinklab-SJT Crossformer提出一个新的层次Encoder-Decoder的架构,如下所示,由左边Encoder(灰色)和右边Decoder(浅橘色)组成,包含Dimension-Segment-Wise (DSW) embedding,Two-Stage Attention (...

% correlation in the aggregate data is driven by the behavior of the data % over scales of four to eight quarters. When you consider the data over % different time periods (scales), there is no significant correlation. %% Wavelet Cross-Correlation Sequences -- Leading and Lagging Variables %...
HT(Time-dependent Hurst exponent) MFDFAandMFDCCAalso provides methods for the mass exponent τ and the multifractal spectrumf(α). DCCAhas methods to compute the cross-correlation coefficient ρ_DCCA and the corresponding confidence intervals. ...
