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.
