covariance of equal date values
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I need to count the covariance of two time series. Both of them contain
the dates' vector and vector of values. But the dates are not the same. It
means some dates of first ts are not in the second respectively. And I
need the covariance of same dates, of course.
Could anyone help me, please?
Thank you.
