Using the Sample node, this was made 50% / 50% before running through a Decision Tree node. I understand the Decisions node allows for adjustment of Profit based on prior probabilities, however I read that classification rates are not adjusted.&nbsp;</P><P>&nbsp;</P><P>How do I adjust my True Positive Rate / True Negative Rate in this scenario given the oversampling and prior probabilities?</P> Tue, 23 Aug 2016 19:59:53 GMT https://communities.sas.com/t5/SAS-Enterprise-Guide/How-to-adjust-TPR-TNR-for-oversampled-data/m-p/293564#M20054 jbencina 2016-08-23T19:59:53Z https://communities.sas.com/t5/SAS-Enterprise-Guide/How-to-adjust-TPR-TNR-for-oversampled-data/m-p/304490#M20653 adjacent to the decision weights tab in the same data source step is a target priors tab for just that.
