Dear Allin,
This script doesn't crashes
Thanks, Oleh. So know we know, by the empirical method, that running
a double loop over p and q (with a max of p=2, q=2) in arma
estimation is not in itself a sufficient cause of a crash on Windows
XP.
The forensic method in software development often proceeds by
seeking the minimal program that provokes a crash. So now we need to
look a little further. Does it make a difference if the loops start
at p=0, q=0, rather than p=1, q=1 as in my script (all else
unchanged)?
Thanks very much for helping to debug this issue.
