Compute Variable

[Kam T]

Greetings - is it possible to compute a new numeric variable (y) from pre-
existing numeric variable (x) which is coded by a 2-level categorical variable
(n) i.e., y=x(n=1)/x(n=2). I am using SPSS 18, and I suppose I can copy paste
my data into spreadsheet and do this and bring back to SPSS and recode my new
variable. But it would be so much easier to do everything natively in SPSS;
and I'd be surprised if it were not possible! Thanks in advance. Kambiz

I am not sure I understand what you are asking.  Many kinds of data transformations can be done in SPSS.

Can you be more explicit in what you are asking?

Give more detail.

 

What values does x have now?  What values do you want y to have? 

 

You can probably do something in syntax with COMPUTE, possible followed by RECODE, but we need some sample data (even artificial).

 

There are some syntax based tutorials on my website, which has a search facility.
