When I try to run the Start Groups node it says "Missing a start groups or end groups node". What does this mean? I am trying to run a Start Groups node which is connected to a tree, which is connected to an End Groups node.. How can they be missing when they are both there and connected??</P> Wed, 17 Nov 2021 20:30:29 GMT https://communities.sas.com/t5/SAS-Data-Science/SAS-EM-I-am-trying-to-loop-a-number-of-decision-trees-using-a/m-p/780867#M8969 EC27556 2021-11-17T20:30:29Z Re: SAS EM - I am trying to loop a number of decision trees, using a different target variable each https://communities.sas.com/t5/SAS-Data-Science/SAS-EM-I-am-trying-to-loop-a-number-of-decision-trees-using-a/m-p/780896#M8970 <P>Hello,</P> <P>Shouldn't you run the End Groups Node instead of the Start Groups Node?</P> <P>Koen</P> Wed, 17 Nov 2021 22:27:40 GMT https://communities.sas.com/t5/SAS-Data-Science/SAS-EM-I-am-trying-to-loop-a-number-of-decision-trees-using-a/m-p/780896#M8970 sbxkoenk 2021-11-17T22:27:40Z
