Yes, provided that A11 is empty. Otherwise use =CORREL(A1:A8,A3:A10).
Note that the two offset arrays must be the same size.

Thanks Jerry.

To calculate higher lags can you just move the second range downwards, eg
lag 2 =CORREL(A1:A9,A3:A11) ?

If your data is in A1:A10, then =CORREL(A1:A9,A2:A10) is the lag 1
autocorrelation.

Hi

Does anyone know how to calculate an autocorrelation function in Excel?!

Thanks!
