Dear Stata-listers,
Is there a better way of executing the code below which assigns
individuals into the Non-smoker and Smoker categories based on the
probability of smoking in pregnancy?
****0=Non-smoker, 1=Smoker***
**** Assuming 84% of women do not smoke during pregnancy
**** Johnston V, Thomas DP, McDonnell J, Andrews RM. Maternal smoking
and smoking in the household during pregnancy and postpartum: findings
from an Indigenous cohort in the Northern Territory. Med J Aust. 2011
May 16;194(10):556-9.
gen smoker1=int(1+(50000-1)*runiform())
gen smoker=0 if smoker1 < 42000
replace smoker=1 if smoker1 >= 42000
label define smoker_label 0"Non-smoker" 1"Smoker"
label values smoker smoker_label
label variable smoker "Smoking status"
drop smoker1
Kind regards,
Gwinyai
