Hi All,
I am really excited about the CEM and want to use it for a lot of future studies. I have two questions:
1. Which software performs the fastest comparing R, STATA and SAS macro?
2. I want to get a matched id so that I know which pair (case and control 1to 1 match) are matched together? Is it possible to obtain a data set has that column in the SAS macro or STATA?
Thanks a lot!
Fang
