Sequence Lag Correlation Analysis
Compare the cross-correlation and overlap of the overlapping segment cosine similarity between the two sets of numerical sequences at different sampling.
Sequence Lag Correlation Analysis User manual
- Fill in the parameters or select the file according to the form, and check the unit and format first.
- Compare the data of a set of delayed sampling points to see the relevant changes of the timing shift position.
- Click the processing button to view the results, you can copy or download and save.
Calculation method and processing rules
Align X[i] to y[i−k], and accumulate the overlapping parts, and calculate the energy normalization value at the same time.
scope of use
Each sequence can be at most 512 points, with no decreasing mean; short overlap can produce inflated normalization results, which are not equivalent to proof of causality or delay.
Will the input content be saved on the server?
This tool handles input in the browser, and does not upload files or form content. Typing practice scores are only saved in the native browser.
Why may the result be different from other tools?
Each sequence can be at most 512 points, with no decreasing mean; short overlap can produce inflated normalization results, which are not equivalent to proof of causality or delay. Please compare the input unit, rounding method, applicable rules and data version first.
