Since -bitobit- is a user written command you should try contacting
the author as he may not be a member of Statalist.
At least the -tobit- model you can calculate the other predicted
values (pr(a,b), e(a,b), ystar(a,b) ) from the fitted values
For example:
sysuse auto,clear
tobit mpg gear, ll(17)
predict p, pr(17,.)
predict e, e(17,.)
predict yst, yst(17,.)
predict yhat,xb
local l ((17-yhat)/_b[/sigma])
gen my_p = normprob(-(17-yhat)/_b[/sigma])
gen my_e = yhat + _b[/sigma]*normalden(`l')/normal(-`l')
gen my_yst = my_p*my_e + (1-my_p)*17
sum p my_p e my_e yst my_yst
