SAS listers:

I have a question regarding weighting. My data is a
stratified sample. For example, there are 3 stratum:
the 1st one was drawn every one out of 4; the 2nd one
was drawn every one out of 5; the 3rd one was drawn
every one out of 7. If I run proc reg or proc logistic
just on this data I can use the sample weight (4,5,7)
in the weight statement. However I have to match this
sample with another data before I can run Proc, and
the match rate is about 55%, that is to say not every
record in the current sample will be in the final
analysis. So my question is, do I need to
modify/recalculate the sample weight (and how?) OR
still use the original weight (4,5,7) in th weight
statement?
Thank you!

Slade
