Only one -gen- statement is necessary/allowed for "brand", such as - gen str
brand = "Cheerios"-. Subsequently you replace via - replace brand =
"Wheaties" in 2-...

Betreff: Re: AW: st: string variable question
Hi,
Sorry, but I'm not making myself clear. Let me try again. Here's the data:
A1 A2
1.35 -2.48
1.50 0.56
0.75 -1.2
...
I want to add a third variable, brand, that has nothing to do with the
specific numbers for A1 and A2, but rather with the rows. So, I want
A1 A2 brand
1.35 -2.48 Cheerios
1.50 0.56 Wheaties
0.75 -1.2 Frosted
...
A1 and A2 come from an MDS estimation by converting the e(Y) matrix to
variables. I now need to add the brands for further processing. It
seems I should be able to do something like
gen str brand = "Cheerios" "Wheaties" "Frosted" etc
But it doesn't work, unless I just mistyped something. Hope this helps
clarify what I need. I really appreciate the help.
Thanks,
Walt
