I have a problem with my project. I have 1000 data and I used it as training data to forecast with Timeseries. My lecture suggested me to use value for determine cut off or not, rather than use graph.

Here's my ACF Value.

Is there any syntax in R to know the upper limit and lower limit of ACF?

I have a sample of 1000 data points and I used it as the training sample to forecast with Timeseries. My lecture suggested me comparing the ACF with its critical values (upper and lower) numerically rather than looking at the graph.

Here are my ACF values:

Question: How do I come up with the upper and the lower critical values for the ACF? Is there any function in R to yield these values?

Thankyou in Advanced. If you don't understand, let me know. :D
