Re: st: margeff/margins discrepancy

[Michael Norman Mitchell <Michael.Norman.Mitchell@gmail.com>]

Dear Richard

  Indeed, I am using a different version of -margeff- than you are. I 
am using this version from

http://www.stata-journal.com/software/sj5-3/
Stata Journal volume 5, issue 3

and here is the -which- information

. which margeff
c:\ado\plus\m\margeff.ado
*! Marginal effects for categorical dependent variable models
*! This version: 22 April 2005 (Stata Journal submission)
*! Author: Tamas Bartus (Corvinus University Budapest)

  I don't know if that helps to solve this, but there it is :)

Best regards,

Michael N. Mitchell
