| Subject | st: how to use treatreg |
| Date | Fri, 30 Jul 2010 12:35:08 +1000 |
Dear All, I am going to use treatment effects model to address the self-selection problem in my models. when using "treatreg dep indep, treat (dep_t = indep_t)", the result shows "invalid treatment values. only 0 and 1 are allowed". in fact, my treatment indicator which is specified in () is a dummy with 1 or 0 values only. Could you please advise me why this happens and how i can correctly use this command? Many thanks!
