Consistent results are obtained by comparing the new method with the detrended cross-correlation coefficient蟻DCCA. Therefore, the proposed approach is reliable, reasonable, and applicable, and can examine the d
The vertical crosscorrelation between two time series of wind speed in different heights gives information about the slope of the eddyfront. The larger the distance between the two heights, the weeker is the peak of the crosscorrelation as is shown in figure 3. The maximum of the crosscorrelat...
One way to decide this is to look at the correlation between the two time series at various lags and identify the lag that produces the highest correlation coefficient, or assuming that there can be an inverse correlation between the two time series, the highest correlation in absolute value. ...

The detrended time-lagged cross-correlation analysis A time-lagged DCCA cross-correlation coefficient is proposed with objective of quantifying the level of time-lagged cross-correlation between two nonstationary time series at time scales. This coefficient, ρ(n, τ, R, R ), is defi...
Given the following two time series (x, y; see below), what is the best method to model the relationship between the long-term trends in this data? Both time series have significant Durbin-Watson tests when modelled as a function of time and neither are stationary (as I understand the ...
Cross-correlation is a statistical technique that assesses the similarity or dissimilarity between two or more time series data. Time series data refers to a set of observations recorded over a specific period, such as stock prices over days, weeks, or months. By analyzing multiple time series ...
Cross-correlation is generally used when measuring information between two different time series. The possible range for thecorrelation coefficientof the time series data is from -1.0 to +1.0. The closer the cross-correlation value is to 1, the more closely the sets are identical. ...
Functions for cross correlation of unevenly sampled time series. Sour is an R package for estimating the cross-correlation between two time series which may be irregularly and/or non-simultaneously sampled. It isalso a cocktail: Method The CCF is computed using one of two methods: ...
Test I shows the advantages of DPCCA in handling non-stationary signals, while Test II reveals the “intrinsic” relations between two considered time series with potential influences of other unconsidered signals removed. To further show the utility of DPCCA in natural complex systems, we provide...
