Dear Marteen,
I just tried your formula with stata 8 but I get a strange message
after:
global_g.new: class member function not found
Any idea what's wrong?

Dear Aga,
If you had Stata8 you could have used my earlier post:
-twoway function y = exp(-_b[mpg]*x- _b[mpg2]*x^2), range(12 41)
ytitle("odds") xtitle("mpg")- gives you the odds of belonging to a
group versus all `lower' groups.
now you could do something like:
version 7
sysuse auto
gen mpg2 = mpg^2
ologit rep78 mpg mpg2
preserve
drop _all
set obs 31
gen mpg =11 + _n
gen odds = exp(_b[mpg]*mpg + _b[mpg2]*mpg^2)
graph odds mpg, c(l)
restore
I forgot the correct -graph- syntax for stata7 to make the pretty, but
this should get you started.
