Thanks. This would be exactly what i am looking for. But it seems like this command was introduced in Stata 11 and i am stil working with Stata 10. Can i download this function somehow, so i can use it in Stata 10? Or is there a similar function?

Thank you very much, it seems to work like a charm. Only Problem is, that the some Model-names contain spaces and then Stata says "invalid name". I know there is a command to relpace all the spaces by an underscore, but i can't find it anymore. Anybody knows this command? Thanks

how about

 levelsof traded_model, local(traded)
 levelsof new_model, local(new)
 local onlytraded : list traded - new
 local onlynew    : list new - traded
 local others     : list onlynew | onlytraded

 replace traded_model="others" if inlist(traded_model,"`others'")
 replace new_model   ="others" if inlist(new_model,"`others'")

Hello

I have a huge dataset containing automotive brand-swiching data. I have a
variable called traded_model and another variable called new_model. in order to output a symmetric swiching matrix i need to identify all the expressions
that are eigther only in traded_brand or only in new_brand and replace
the
expression with "others". For example a model called "318d" exists in
traded_model but not in new_model, so all the "318d" should be replaced
by
"others".

Does anyone have an idea how i can programm that? I dont get it to work, and
doing it manually is close to impossible as there are more than 1000
different model names.

Any help is much appreciated, thank you.
