I have been without Internet access for a couple of weeks (in the US
AT&T is now competing with the cable companies and has succeeded in
emulating the cable TV companies' terrible service) and I missed the
beginning of this discussion. Is there a reason that you have not
used the example in the NRAIA package to obtain that model fit?
A quite simple reason.
My fault: I did not know the existence of the library, so I was trying
to build the example (and the data set) on my own.
Try
install.packages("NRAIA")
library(NRAIA)
example(Chloride)
That gets you the data and the model fit without the AR1 correlation.
I guess that I didn't put in the general optimization in that example
yet.
Could you be please so kind to give me some hints on it ?
