Nobody prevents you from creating the dummies beforehand via -tab, gen()-. The interaction would have to be created by hand, though. See also

-xi- automatically prevents you from falling into the dummy trap and overrides previously created "_I" vars, which is a neat feature...

Betreff: st: variable name

Dear Stata users:

I have a simple question here. When I use xi (Interaction expansion), I got the following report. I am wondering if there is a way to keep the original snp names. For example:

_Irs1Xrs~1_1  ==> _Irs1234567_1Xrs7654321_1


Thanks! 

xi: logit case sex i.rs1234567*i.rs7654321, or
