Dear Friends,

I am doing Difference-in-differences analysis with repeated cross-sectional data. I have both continuous and binary data. I found STATA syntax for continuous data but I am not able to find STATA syntax for binary data. I would appreciate if somebody can help me. I am using STATA 12 and SPSS 20. I have heard that SPSS can not perfom that regression that's why i am asking for STATA but if you have SPSS syntax would be great if you can share as well.

Thanks for your consideration.
