SAS EM - I am trying to loop a number of decision trees, using a different target variable each time

[EC27556]

I am using the Start Groups and End Groups nodes. 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??

Hello,

Shouldn't you run the End Groups Node instead of the Start Groups Node?
