Linearity of IV's to log odds

[mllx4eg5]

I have a variable 'sexshun', when i try to run the following syntax;

COMPUTE sexshun_LN=LN(sexshun).
EXECUTE.

I get this error message:

>Warning # 602
>The argument for the natural log function is less than or equal to zero.
The
>result has been set to the system-missing value.

When I run a regression to see if the interaction is significant, the
sexshun_LN*sexshun is not included in my regression.
Does anyone know how to fix this.

Thankyou

I think your original post was delayed in being distributed to the mailing
list--or at least in appearing in the Nabble archive.  By the time I saw it
(in Nabble), some discussion of your question has taken place in another
thread:

http://spssx-discussion.1045642.n5.nabble.com/linearity-of-independent-variables-to-log-odds-td5738355.html

I suggest that further discussion be restricted to that thread.
