对于两个(x和y)随机过程而言,交叉相关性(cross-correlation)这个概念表示的这两个随机过程的相似程度;delta_xy(t') = E[x(t)y(t-t')]。 在某个时间差t‘=T 的时候,发现delta_xy 出现极大值的时候,说明x(t) 和 y(t-T) 的相似性很高。 赞(1) 回复 moody 楼主 2020-09-16 06:24:06 楼上...

Lag Effects: If a lead-lag relationship exists, compute the cross-correlation function to find the correlation at different lags. Example For and : , . Numerator: , Denominator: . (perfect positive correlation). When to Use Alternatives Spearman’s Rank Correlation: For monotonic but non-linear...
At the final stage, the cross-correlation and lag of each beat with the ensemble average was computed, any beat with a non-zero lag to the ensemble average was circularly shifted to have zero lag. Any circularly shifted beat that had a correlation coefficient < 0.8 was assigned an ...
Colony candidate selection by differential analysis When a new frame was acquired at timet, it was cross-registered to the previous frame at timet − 1 and then digitally back-propagated to the sample plane44,45to obtain the complex light field ...
Function 'ccf' computes the cross-correlation or cross-covariance of two univariate series (stats) diff.ts(): returns suitably lagged and iterated differences (stats) lag(): computes a lagged version of a time series, shifting the time base back by a given number of observations (stats) Few...
