st: pweight or fweight?

[Andrea Bennett <mac.stata@gmail.com>]

Dear all,

I'm getting a little confused with the weight options. I've  
constructed the following weight: A / B=weight, with A==share in true  
population and B==share in sample. These weights refer to U.S. states  
while the observations are single individuals.

Which weight option should I use in the regress command? I think it  
should be the -pweight- but since I've never worked with weights  
before, I thought I ask!

Many thanks for your considerations,

Andrea
