Inverse Prior Weights

Hello,

Is there any SAS paper explaining the reason and benefits of the inverse prior weights (central decision rule) for oversampling purposes?

Can you please send relevant linkes?

Thnaks in advance,

Andreas

Re: Inverse Prior Weights

There are tons of papers out there on oversampling, undersampling, weighting of observation and other techniques of this kind. One of my favorite is this one:

http://www2.sas.com/proceedings/forum2007/073-2007.pdf

It talks about oversampling starting on page 6.

Other articles I like are these two by Gordon Linhoff:

If you're looking for more technical details, just google the topic and you'll find a lot more.
