Both the P_DV &amp; V_DV variables are created. P_DV is the predicted value of the dependent variable. Likewise, V_DV is the validation value of the dependent variable, but I am not so sure as to why they would be different on a record basis.</P><P></P><P>But what is the R_DV variable?</P><P></P><P>Thank you.</P></BODY></HTML> Fri, 14 Aug 2015 18:26:01 GMT https://communities.sas.com/t5/SAS-Data-Science/Save-Data-Node-in-Enterprise-Miner-quot-R-quot-Column/m-p/199410#M2624 Zachary 2015-08-14T18:26:01Z Re: Save Data Node in Enterprise Miner - "R_" Column https://communities.sas.com/t5/SAS-Data-Science/Save-Data-Node-in-Enterprise-Miner-quot-R-quot-Column/m-p/199411#M2625 <HTML><HEAD></HEAD><BODY><P>R_DV is the residual, DV - P_DV.</P><P></P><P>And just a little more about V_DV since that can be confusing.&nbsp; The V_ variables are only calculated for decision trees since for all other models, the V_ and P_ columns would be the same.&nbsp; For decisions trees, V_ represents the proportion of validation obs in the same leaf as the current obs. that have a certain target level for a classification tree, or the mean of the target for the validation obs. in the same leaf as the current obs. for a regression tree.</P></BODY></HTML> Fri, 14 Aug 2015 19:14:34 GMT https://communities.sas.com/t5/SAS-Data-Science/Save-Data-Node-in-Enterprise-Miner-quot-R-quot-Column/m-p/199411#M2625 WendyCzika 2015-08-14T19:14:34Z
