Any Pearson correlation equivalent for time series data?

E. Bernardo
Dear All,

Is there a Pearson correlation equivalent for time series data in SPSS Forecasting?
I already posted this issue some few weeks ago, but I need to re-post the same by rephrasing the question so that everybody understands.

Thank you.

Maguin, Eugene

What are you asking for? Let’s be specific. You have one or more series, call them X, Y, Z, etc. So you either compute auto correlation as lag k or cross correlations at lag k. I looked at the algorithm book and the sample auto correlation, computationally, is a pearson correlation. The variance formula is different however.

Gene and ALL,

Thank you for your helpful comments. The cross-correlation at lag k is the one that I have been looking for.  However, I have a follow-up question. As cited in the SPSS manual, "the best approach is to create time series model for both series and then cross-correlate the residuals". I dont understand the rationale why we cross-correlate the noise residuals.  Can somebody enlighten why the NOISE RESIDUALS are to be cross-correlated, rather than the original time series data?

Thank you.
E. Bernardo
