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

I've tried and it really doesn't matter...
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.
