Hi folks,
I have two varibles: weight and height of respondents in 1989.
weight1998 float %9.0g
height1998 float %9.0g
I want to create a new variable:
gen BMI = weight1998/(height1998^2)
My little problem is that: BMI takes strange values if weight1998 is
missing. Could anyone tell me why? Thanks a lot!
height1998 weight1998 BMI1989
