Correlation Matrix for Two-time Series

Answer:

Using the cross-correlation (XCF(.)) and the Backshift/Lag (LAG(.)) functions, you can compute the correlation factors for any lag orders.

Example: Let's assume we have two-time series; Series A and Series B
Series A is stored in cells B1:B200
Series B is stored in cells C1:C200

To compute the cross-correlation matrix (R), we use the XCF(.), and LAG(.) functions as follow:
R(j,k) = XCF(LAG(B1:B200,1,j),1, LAG(C1:C200,1,k),1)
