Hi, i was trying to compute the summary statistics for a set of categorical variables and used asdoc to export it to use .

asdoc su i.qd1 qd7 i.edu i.qd10 i.area5 i.pop_com

As im working with categorical variables i was looking for the mean/perchentage only so i added the specification but then i am getting an error that says "factor-variable and time-series operators not allowed"

asdoc su i.qd1 qd7 i.edu i.qd10 i.area5 i.pop_com, stat(mean)


Thanks in advance
