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...

Time lag Time-lagged DCCA cross-correlation coefficient 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....
One of these methods is based on the estimation of the time lag at which the cross-correlation function (CCF) estimation reaches its maximum value. The uncertainty of the peak location refers to the smallest determinable flow velocity modulation, and therefore the standard deviation of the time...
showxcorrx- Like rapidtide, but for single time courses. Takes two text files as input, calculates and displays the time lagged cross correlation between them, fits the maximum time lag, and estimates the significance of the correlation. It has a range of filtering, windowing, and correlation...
To define cells significantly modulated by assembly activities, we cross-correlated the spike count vector of each cell to the activity vector of each assembly (8 s time window). For each cell, we averaged cross-correlograms for different assemblies to define ‘mean cross-correlations to assem...
The choice for lag bin width is more subtle. It's worth mentioning that the DCF doesn't interpolate your data - it interpolates the correlation coefficient according to how you tune the bin width. However, this does not mean you should choose the finest bin resolution you can. If resolutio...
