谢谢大家啊,非常非常有帮助.Mikamika我也觉得是prvalue 命令，不过这个命令不下载spost的话，stata不能识别

可是,当务之急,按照那本书,我要下载spost,但是我键入命令后,没办法下载.

. net search spost
(contacting http://www.stata.com)
http://www.stata.com/websee.cgi?r=2&s=bds&o=w&j=a&k=spost could not be opened f
> or read by copytextfile
r(601);

. net from http://www.indiana.edu/~js1650/stata/
I/O error
http://www.indiana.edu/~js1650/stata/ either
1) is not a valid URL, or
2) could not be contacted, or
3) is not a Stata download site (has no stata.toc file).
r(691);
谁能帮帮我？？？或者谁以前做过这类的回归，教教我怎么办？？？

我咋都用不了findit的功能呢。。导致prvalue之类命令都用不了。。难道是下的green stata10的问题？有人在用那个吗？

不好意思，我想问一下scott long and J Freese's book那本书哪里有下载的，本人急需ordered probit方面的资料，谢谢各位了！！

oprobit y x1 x2 x3
summ x2
replace x2=r(mean)
summ x3
replace x3=r(mean)
predict p1 p2 p3 p4 p5

findit不能运行，可能是因为防火墙

我也很急需，谢谢

since stata10, you can use a simpler but powerful command: "margins".

oprobit y x1 x2 x3
margins y, at((mean) _all  x1=(a b c d e))

请问这个书哪里有的呢？

seems not reach agreement

请问oprobit怎么做的呀
