There is much information on several statistical packages, including 
SPSS, at this site:

<http://www.ats.ucla.edu/stat/>

which covers log linear models for both packages.

If you are unfortunate enough to be stuck using Stata without manuals, 
this web site is your next best choice for instruction. Also, don't 
forget to visit the FAQ at stata.com.

For ttesti, I think you are right. Display to calculate (variance)^0.5 
= sd and then plug in the numbers.
