st: Dtobit after tobit

["Li Chuntao" <chtl@hkusua.hku.hk>]

Dear Users,

  recall my previous mail, i find that, actually dtobit does not work in 
Stata 9. I do not know if this command works in your system.

following is my output:

. sysuse auto, clear
. tobit mpg trunk weight, ll(17)

Tobit regression                                  Number of obs   = 
74
                                                 LR chi2(2)      = 
73.86
                                                 Prob > chi2     = 
0.0000
Log likelihood = -163.74787                       Pseudo R2       = 
0.1840
