Hello,
I'm new to stata and I need help to recode two variables into one. I'm not
succeeding so I'm hoping someone will be able to help me out.
I have two variables:
age at first poker use (poker) and age of first tobacco use (tobacco).
I want to create a variable (risk_behaviour) with 3 levels that will have
the value labels of 1 = tobacco<poker, 2 = tobacco>poker, and 3
tobacco=poker. I run into trouble with this as stata is treating my
missing values when it calculates it and I can't seem to make it not
compute this when either original variable has missing values.
Any suggestions on the syntax I can use?
Many thanks.
