Dear Statlister,
I want to generate a single unique id to merge files
by using variables: var1 (F1) var2 (F3) var3 (F4) and
var4 (F2), where F shows the integer width (f format).
So, I used
gen id = var1*10^9 + var2*10^6 + var3*10^2 + var4
This is the output from stata and the true id (as it
should be) for the following
example:
var1 var2 var3 var4 id (stata) id (true)
1 2 3452 1 1005452032 1002345201
1 121 34 10 1121033984 1121003410
2 23 156 2 2023155968 2023015602
2 45 3 2 2045003008 2045000302
3 6 4 3 3006003968 3006000403
3 70 8 5 3070008064 3070000805
Why is the stata id different from the true id? Does
stata store numbers in different format?
Thank you!
Tesfayi
