Multiple groups from two variables

[Justin Shinn]

Hello,

I am trying to create a newvar that has 0 and 1 from two variables.

The first variable (var1) is binary (yes = 1, no = 0). The second variable (var2) is a range of values (-2 through +2 at 0.5 intervals; ie. -2, -1.5, -0.5, 0, etc).

For the newvar:

1. I want 0 to be true if var1 = 0 and var2 to be >= -0.5.
2. I want 1 to be true if var1 = 1 and var2 to be >= -0.5.

Notice, this will also be working with missing data. Missing data will be any rows with var2 <= -1, which I don't want included in my future analysis.

Appreciate the help!
Thanks

I believe this code should work:

gen newvar = 0 if var1 == 0 & var2 >= -0.5
replace newvar = 1 if var1 == 1 & var2 >= -0.5

Yup, worked! Thank you.
