topic How to fit a decision tree model in SAS Enterprise Miner using data partition? in SAS Data Science https://communities.sas.com/t5/SAS-Data-Science/How-to-fit-a-decision-tree-model-in-SAS-Enterprise-Miner-using/m-p/575802#M7910 <P>I have been trying to fit a decision tree model by using a data partition. As long as none of the Training, Validation and Test allocation is set to 0, the model runs fine. However, I want to divide the data into only Training and Test, thus if I set Validation to 0, the data partition node runs fine but the decision tree node gives a run time error. Would appreciate if someone could help me out with this.&nbsp;</P> Tue, 23 Jul 2019 13:46:47 GMT ylohana 2019-07-23T13:46:47Z How to fit a decision tree model in SAS Enterprise Miner using data partition? https://communities.sas.com/t5/SAS-Data-Science/How-to-fit-a-decision-tree-model-in-SAS-Enterprise-Miner-using/m-p/575802#M7910 <P>I have been trying to fit a decision tree model by using a data partition.

However, for something like 80:20, this is the error I'm receiving, "ERROR: Run time error was encountered. The system error returned was 1012".<BR /><BR />Thanks!
