| Sep 6, 2020 at 8:04 | comment | added | Chris | Very interesting, I did not think about multiplication by such function to obtain simple zeroes. So indeed, it is not always possible. I just need to make this assumption then. I wonder if it says something interesting about the covariances functions that cannot be root squared that way. | |
