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

还是不行依旧报错

是不是moremata 放的文件夹不对？

我也遇到了同样的问题，不知楼主是否已经解决这个问题，求助

没有，后来没做了
