Dear helpers,
When I use ar to fit the data with length 180, I have the following
error:
ar(x,method="burg")
Error in acf(x, type = "covariance",lag.max=order,plot=FALSE):
lag.max must be at least 1
If I use
ar(x), then I have
Call (x=x)
order selected 0 sigma^2 estimated as 5374
Obviously I missed some points for using ar.
This is R 1.7.0 under Redhat Linux 9.0
Thanks in advance.
