Hi again
I just need to be sure that I understand a couple
of things in your proposed command as it is not
working exactly as I want it to yet:
1) When you type L.flow is that referring to the
Value in cell [_n-1]?
2) you type flow = (shift == - 1)*..... and then + (shift == 1)*...
Adding the + there and then (shift == 1) means Stata should
execute the last command only if the (shift == 1) is true?
The 2/1 at last means starting in cell 2 and continue in
Steps of 1, right? As you probably understand I am
Kind of new to programming syntax in Stata.
Thanks,
You are very helpful!!

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.
