Generalized Linear Model

[drfg2008]

SPSS 20

The procedure <Generalized Linear Model> has a <scale weight> variable (under <response>).

My questions:
If I want to weight certain cases more than others, am I right to use this field for?
If I want to weight those cases with a factor of let's say 10% more and the others with let's say 10% less, would I simply compute a variable, with 1.1 for those cases to be upweighted and 0.9 for the others and then use this variable as the scale weight variable?


As in syntax:
