Subject   st: creating two groups with identical distribution of one variable
Date   Wed, 14 Oct 2009 13:41:09 -0700

Hello Statalist folks,
Using the following simulation, I create two groups: #1 = mean age 50, #2 = mean age 60. I'm seeking some guidance on how to create variable newgroup, such that newgroup A and B will have equal age distribution.

clear
set obs 1000
gen group=1
replace group=2 in 501/1000
gen id=_n
set seed 12358
gen age = 50+10 * invnorm(uniform()) if group==1
replace age = 60+10 * invnorm(uniform()) if group==2
hist age, by(group)
