谢谢您的关心，是在常规回归后，直接运行命令就可以了么？根据倾向分数分层是人为分的还是电脑自动分层？因为对这个运行不是很了解，所以感觉过程不是很清晰，如果有人做个这个，能否给我发一份执行过的do-file 文件，不甚感激。

If you really want to learn PSM in stata, please refer to the following book:

Propensity Score Analysis: Statistical Methods and Applications (Advanced Quantitative Techniques in the Social Sciences)

It has very good introduction to PSM in stata and has sample programs and examples. You can google the book title and author name. The book has a website to download examples, data and some programs.

I found the book useful, especially the examples.

thank you  very much

谁有这本书啊啊？能不能发给我啊？找不到啊。。
