GLS with nlme
Hello All,
This is my third time attempting to post this message. I don't see it
in the archive, so I'm guessing it is not getting through. If I am
wrong, my apologies.
I am trying to do a GLS regression, (X'V^-1X)^-1X'V^-1y, using the gls()
function from the nlme package. I have the covariance matrix V. I have
been searching for a way to specify the correlation structure
