I am running a model for a problem in insurance domain. The final results show some false positive x and some false negative y. I am using SAS Enterprise Miner for this. Can somebody suggest me how to reduce false positive? I know for this i have to increase the false negative. I want to know two things:
Is there any option in e-miner where I can give more weight to false negative and less to false positive?
Is there any general approach in modeling which tells us any ways to reduce false negatives or is it just a hit and trial approach?
