Thanks Kit, I think your command is going to work. At least its working when trying it out on a Small test-sample. My actual sample has more than 60 000 obs. I have problems in generating a variable I need In the calculations however: I need to generate a variable X2 as a mean of the variable X1 and the next x1[_n+1] til X1[_n+8]. Can this be done using egen? As this variable X2 will be changed it is not very practical to calculate the mean by typing X2=(X1 + X1[_n+1] etc..)/n L -----Opprinnelig melding----- Fra: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] På vegne av Linn Renée Naper Sendt: 27. november 2008 20:41 Til: statalist@hsphsun2.harvard.edu Emne: st: RE: re: if-sentences in Stata Thanks I am looking into your proposed solution right now.

I get the same result. And that result will presumably be meaningless, as a statement like if shift == 1 will ever only reference the FIRST observation of the variable shift. Given what you have outlined as the logic, I cannot imagine that this could be useful. Please see my proposed solution.
