Negative value

Angela Murphy
Hi All

Is there some way to remove negative signs from a list of values (convert
them to positive) in syntax without having to square and then find the
square root?

Thank you

Re: Negative value

Boer, CPJ de
Hello Angela,

There is a function for that namely ABS
-----------------------
Arithmetic Functions
[...]
ABS(arg) Absolute value. ABS(SCALE) is 4.7 when SCALE equals 4.7 or -4.7.
-----------------------

As is written onpage 46 of the SPSS 14.0 Command Syntax Reference.

You invoke it via the menu: Help-->Command Syntax Referenec.

Perhaps you want to stuf it into an other variable so you don't change the original data:

COMPUTE varpos = ABS(varpos_ro_neg).


With regards,

Kees de Boer
