You are apparently fitting a series for which the selected order is zero,
and ar.burg is not designed to cope with that (and would in any case tell
you nothing useful). The default method does cope, from your output.
Why are you fitting an AR model to a series with apparently no
correlation?

Dear helpers,

Hi,
where can I find the most up-to-date Debian packages for R and sources in

Are their any special recommendations or instructions for building and
