These questions are answered by the helpfileof -mfx-: 
-mfx- will also work for -probit-, -logit- and 
-tobit-. In case of -probit-, and -logit- I actually 
prefer -prchange-, which is part of the -spost- 
package (see -findit spost-). For -tobit- there also 
exist the -dtobit- user written command (see: 
-findit dtobit-). You can specify the values of x at which 
you want to calculate the marginal effect  with the at() 
option, see -help mfx-.

Subject: st: RE: RE: RE: st: ´ð¸´: st: How to choose a proper model if the dependent variable is within bounds?
how to specify a certain value of x if I want to predict the dy/dx using -mfx- for the certain value of x? And is there any similar postestimation command like -mfx- for -probit-, -logit- and -tobit-?
