time-lagged cross-correlation between two nonstationary time series at time scales. This coefficient, ρ(n, τ, R, R ), is defined based on a DCCA cross-correlation coefficient ρ DCCA (n). The implementation of this coefficient will be illustrated through selected time series of...
This retrospective study evaluated windowed time-lagged cross-correlation (WTLCC) matrices for describing cerebral hemodynamics–ANS interactions to predict outcome, enabling identifying high-risk patients who may benefit from enhanced monitoring to prevent complications. Methods The first experiment aimed to...
Possible physical mechanisms for the correlation between NDVI and P/T NDVI on the Loess Plateau increased significantly during 1982 to 2010, especially in autumn. Similar results have been found by Zhao et al., 2017, Li et al., 2017a, Li et al., 2017b. As demonstrated by previous studies...
To analyze the aggregation of data, the following interrater agreement and interrater reliability indeces were calculated: rwg(j)and intraclass correlation coefficients (ICCs; Bliese2000). The rwg(j)index comprises values from 0 (no agreement) to 1 (perfect agreement). To interpret the results,...
To determine the time lag using the proposed optimal correlation coefficient method, we calculated the correlation coefficient between the streamflow in the LYR and the streamflow at Xiaolangdi station for a total of 59 high streamflow events. The analysis was performed within a time lag range of ...
In general, the larger the dynamic effect and the smaller the correlation effect, the wider the OLS-superior range. Jackknife Bias Reduction The jackknife procedure is a cross-validation technique commonly used to reduce the bias of sample statistics. Jacknife estimators of model coefficients...
cross validation dataset, and testing dataset are obtained. Optimal performance is obtained for training 80%, cross validation 15%, and 5% testing. The correlation coefficient on test dataset is found as 0.9984 and 0.9973 for noise signal and EMG, respectively. MSE for EMG signal and noise is ...
The cross-sectional results support positive associations between all measured categories of perceived leadership behaviors and employee safety behaviors, with bivariate correlation coefficients ranging between 0.25 and 0.55. When controlling for respondents’ levels on the constructs at T1, the time-lagged ...
