Hi there, I am wondering how R calculates the acf too?
I have a data set of approx 1500 returns when I calculate the lag 1 autocorrelation in excel I get a value of -0.4 but in R its approximately -0.18? I have cross checked with PC give and PC give agrees with excel? I'm sure its just some kind of scaling but it would be nice to resolve this discrepency!
