Howdy,
In SPSS, there are 2 ways to weight a least squares regression:
1. You can do it from the regression menu.
2. You can set a global weight switch from the data menu.
These two options have no, in my experience, been equivalent.
Now, when I run lm in R with the weights= switch set

It would appear that the SPSS procedure would then give exactly the same
point estimates of the parameters, and change the inference structure by
changing the ``denominator degrees of freedom'' from n-p to sum(w) - p.
This seems to me to make little sense ... But then, it ***is***
SPSS. :-)
