I imagine SAS uses the trivial as you say calculation of sum(weight times
variable value)/sum(weights), so it does not calculate an individually
normalized weight; but who knows.  Perhaps in some of the more complex
statistical calculations it might need to...  Generally I provide my own
normalized weight first to make sure things are as expected... if I have
weights that are not normalized, probably it's for a good reason and I'd
rather SAS leave them alone.
