可解决,但xtptmh出现了其他问题

可能是xtptm方面的

我做的时候也是接连的问题啊。。。

As I commented elsewhere...

The problems can be solved using steps below:
1. download xtptm
2. unrar/unzip the file to a specified location
3. read read me.txt
4. copy all files in the working directory - should be in ado folder of Stata program folder
5. download moremata - type - findit moremata - in stata and download all relevant files
6. open ado file using ado window inside stata and run both xtptm.ado and stradd.ado
7. open your data in stata
8. run xtptm command to estimate your model
9. GOOD LUCK
