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
