Dear statlister,
I need to generate a new variable that have the values of an
old one if a third variable has a certain value, othewise a
missing value.
Let's say we have two variables var1 and var2, I would like to
generate a var3 that has the value of var1 but only if var2
has a certain value otherwise not.
Can you suggest some command?
Thank you
Caterina
