Betreff: st: dummy variable name from a string variable
I want to create 10 dummy variables based on one string variable
"city", which lists the city codes (like NY) of 10 cities. I can do
this simply by (after encoding the city variable):
tabulate city, gen(citydummy)
This would create citydummy1 to citydummy10. What I want is to suffix
each dummy with city codes, listed in the variable 'city' , so I have
the dummy variables named from, for example, citydummyNY to
citydummyAM.
The city variable has multiple occurrences of each code. I have had a
look at -renvars- but I don't think that alone will solve my problem.
Any ideas?
Tom.
