Dear Sir and Madam,
I am a beginner. I want to ask how to add another boundary into the second graph about ACF and PACF for 2 years data, the result should look like the last graph. Another boundary is something I circled in the first graph.
I imported the data into R. Then, I used the the functions of Acf() and PAcf() of the forecast package (library(forecast)) to get the second graph.
Then I used the function of ac.test() of the testcorr package(library(testcorr)) to get the values of the table.
By the way, I got the last graph by running testcorr package in EViews11. But it did not give the result of PACF.
I want to make ACF and PACF functions with two boundaries (both standard CB and robust CB) in R.
Is there anyone who can advise me? I will be grateful.
