斑竹大人更是应该知道的，你问版主大人

不懂那个
你可以先用那个命令的例子看看是否可以运行
如果可以，那么就是你自己的命令的问题了

多谢回复~
貌似可以运行，但是得到的结果不太对。如下：

Two-sample Fisher-Pitman randomization test


Minimum time needed for exact test (h:m:s):  .:.:.
Reverting to Monte Carlo simulation.
progress: |........................................|
r(20);

. sysuse auto
(1978 Automobile Data)

. fptest price if _n>40 & _n<60, by(foreign)
Two-sample Fisher-Pitman randomization test


Minimum time needed for exact test (h:m:s):  0:00:06
progress: |........................................|

theta = mean[ price(foreign==0) ] - mean[ price(foreign==1) ] = -1.8e+03

Test of Ho: price(foreign==0) = price(foreign==1)

Exact  two-tailed p = 0.06013
Exact  lower-tail p = 0.03521
Exact  upper-tail p = 0.96481

用我的数据跑出来就是下面这个结果，结构上比较像，但是结果出不来。你知道是什么原因么？
