The prototype of ar.ols() is

ar.ols(x, aic = TRUE, order.max = NULL, na.action = na.fail,
            demean = TRUE, intercept = demean, series, ...)

demean: should the AR model be for ‘x’ minus its mean?

intercept: should a separate intercept term be fitted?


I wonder what differences are between demean and intercept? Thanks!


Question: EBS volume on AWS
Answer: I am no filesystem expert but your volume that you restored to is not formatted to utilize the 50 GB. In windows you need to expand the drive to utilize the full space of the larger Physical volume. You will need to find out the Linux command line version to make your xvde1 utilize the 50 GB. Ebs volumes are raw disks that need are not pre formatted.

!--------snapshot restored----------!------------raw blocks -------!

I will try to look into my onenote archive. I could of sworn that I documented this for one of my systems. Until then just look up expanding to larger ebs volume after snapshot restored. If I find it I will post it if not you need to search for it.
