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
ta age

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
