Dear Stata-listers,
I am trying to generate dummy variables based on two variables with multiple categories in each.
The dummies need to represent each unique combination of the two variables.
UserID Techlab UserTechD1 UserTechD12 UserTechD13 UserTechD14 UserTechD15 UserTechD6 UserTechD7 UserTechD8
(Comb: 11) (Comb: 21) (Comb: 22) (Comb: 23) (Comb: 31) (Comb: 32) (Comb: 43) (Comb: 51)
1 1 1 0 0 0 0 0 0 0
2 1 0 1 0 0 0 0 0 0
2 2 0 0 1 0 0 0 0 0
2 3 0 0 0 1 0 0 0 0
3 1 0 0 0 0 1 0 0 0
3 2 0 0 0 0 0 1 0 0
4 3 0 0 0 0 0 0 1 0
4 3 0 0 0 0 0 0 1 0
5 1 0 0 0 0 0 0 0 1
The tabulate: generate command uses only a single variable to create the dummies; not sure what to do when there are multiple variables.
Any help is most appreciated.
Best,
Mukund.
