Am I missing something? Doesn't the Greenwood formula give this to you, and isn't it in the ltable command?

Either use frequency weights (first example) or -expand- to the required
number:
*******
clear*
inp int(age number)
0 2000
1 1900
2 600
end
list, noo
ta age [fw=number]
expand number

Subject: st: calculating standard deviation of age at death from period life
tables
Dear Statalist users:
I want to calculate the standard deviation of age at death from period
life tables:
So I know how many people died at age x, where x runs from 0,1,2...110:
For example, in 2004 in the US people 2000 died at age 0, 1900 at age 1,
600 at age 2, etc.
What I think is the right way of calculating is:
To generate a new variable that contains 2000 times 0, 1900 times 1,
600 times 2 etc...
But I don't know how I can generate this new variable in Stata most
efficiently...
Thanks a lot for any hint!
Regards,
Johannes
