varwg.smoothing.crosscorr

varwg.smoothing.crosscorr(data1, data2, lag=1, window_len=100)[source]

Moving crosscorrelation. Returned array has the same length as data. This is achieved by assuming a special kind of periodicity: end of data is prepended to the beginning. You might be better off ignoring the first window_len elements.

Parameters:
data11dim ndarray
data21dim ndarray

This array will be shifted back by ‘lag’ steps

lagint, optional

0 works and gives correlations instead of crosscorrelations.

window_lenint, optional

window length, need i say more?
