Ignacio, thanks, I did it. Importing data (set on 1,2,3 instead of 13/06/2011, 14/06/2011 etc. on file Excel) importing them as cross section instead of series and then not adding the time trend I have the same result. Do you think was I right? Simari On Wed, Oct 26, 2011 at 11:45 AM

Thanks for the answer Allin, the problem that I have is that making the OLS command I do not see the "b" of the Linear regression. At same time I see different results, as R2 for the same regression made on Excel. I'd like to understand why this difference. Regards, Simari On T
