Hi there, I'm using Enterprise Miner 5.3 and am trying to combine the results of several variable selection techniques into a larger pool of "good" variables. I'm using the Decision Tree, Regression and Variable Selection nodes to flag variables as Rejected. What I want is to combine all variables that are not rejected in either or all of the three nodes. Originally I used the Drop node to drop all Rejected variables for each technique and then used the Merge node to combine the remaining variables into a pool to be used for further modeling. This seems to work fine, as evidenced by the succesful running of the Model Comparison node, however it all goes haywire when I try to combine some of my models with the Ensemble node. It then complains with the following warning (and ensuing errors): "WARNING: Apparent symbolic reference EM_SCORE_OUTPUT not resolved." (Log attached) 1) Does anybody have any idea what causes the error? 2) Am I doing the merging wrong? Is there a better way? Thank you for your time, Tijl Kindt ... View more
