Hi, all, I have a question on the "acf" function in time sereis analysis. After I run the function>acf(data);I got two blue lines above and below the x axis. I guess they are confidence inverval borders, right? Could someone tell me what the confidence level is for the blue lines? Is there some way to get the functions of blue lines using R? How about "pacf"? Thank you all. [[alternative HTML version deleted]]
I believe it's actually 2/sqrt(n) where n is the sample size... Interesting.. -- View this message in context: http://r.789695.n4.nabble.com/autocorrelaltion-function-plots-tp3303966p3304490.html Sent from the R help mailing list archive at Nabble.com.
