search for 'predxcat.ado' and you will find a great program to do all sorts 
of these calculations and graphs

Tony,

Do you mean something like this:

sysuse auto,clear

xtile p2 = price, n(5)

tab p2, gen(D)

gen byte gender = uniform() <.5

probit fore D* gender, nocons

replace gender = 0

predict prob_male

replace gend = 1

predict prob_female

collapse (mean)  prob*, by(p2)

twoway line  prob* p2


Hope this helps,
Scott
