Dear Gwinyai, the first trivial step to make your code running is setting the number of observations: ----------------------------------------------------- set obs 100 //or whatever you like or need 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 ----------------------------------------------------- Joseph has already commented on more substantive details.

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 * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/
