Hi there,
I am currently working on a project which requires me to calculate marginal effects. I choose probit model because most variables are categorical variables. I also created dummy variables for all the categorical variables. However, it seems the result is not good(different from the results generated by collegues using stata). I do not think there should be any differences.
Basically, I am using doing it in this way:
proc qlim data=greenedata;
model grade = gpa tuce psi / discrete(d=probit);
output out=outme marginal;
run;
quit;
Is the function of calculating marginal effects only available in SAS/ETS but not in SAS base?
Thank you guys!
