st: Re: Problems with calculating marginal effects for categoricalvariables in ologit models

[MANUELFERN.FLORES@rai.usc.es]

Dear users,

Thanks for all your suggestions. The problem was, actually, like that  
of Lina, the lack of updating of the command margeff. With the latest  
version of Professor Bartus (version number 2.1.8 from 20 April  
2008)it works.

Best regards.
