Hello. I have some time series data and would like to check whether there is
any autocorrelation in my residuals. I generated a correlogram using AC and
found that none of the autocorrelations were outside of the 95% confidence
bands. When I repeated the analysis using ACPLOT I found that some of my
points were outside of the SE bands. Which analysis should I be relying on?
Why is there a difference?
Any tips would be greatly appreciated.
Kind regards,
Stephanie MacNeill
