[R] problem with "acf" function

[Zebouni, Stephane (Exchange)]

Hi List,

 

Does anyone have ever check the results given by the "acf" function?
What formula does it do for lagged autocorrelations and lagged
cross-autocorrelation? My problem is that excel gives quite different
results (sometimes 10% different than acf). Anyone has encountered those
problems before? 

 

 

Kind Regards

 

Stephane
