Dear listers,

I have done a probit with dep. Variabel seenad (0=not seen advertising
and 1=seen advertising) versus 4 different regions, like this

_________________

/* region1 in basis*/
probit seenadTV region2 region3 region4
/*calculating marginal effects*/
Mfx compute
_________________

The mfx gives me dy/dx for discrete changes of dummy from 0 to 1, but I
would like to have the procentage changes in relative probabilities.
This can be done in Excel with the function 'normsdistribution'. Does
anyone know how to do this in stata?

Regards,
Mvh,
Alexander Severinsen
