Hello,
I would like to do cross validation in sas miner. I have a file import node, then a data partition node, transform variables node,start group node, decision tree and end group node in the order listed. However when i ran the start group node it comes up with an error;
"Missing a start groups or an End Groups node".
Would anyone know how to rectify this issue please? I already have both the nodes it says are missing.
And i put this formula in the transform variables formulas;
int((f*(ranuni(0)))+1)
I also set the start groups mode to Cross validation. So not sure where i am going wrong.
Thanks in advance
Dee
Do you mean if you run from the Decision Tree node? Anytime you have Start/End Groups nodes in your flow, you need to run from the End Groups node or a subsequent node since the Start and End Groups nodes have to be paired together.
Try running from the End Groups node; I don't think you can run the Start Groups node without also running the End Groups node in the flow.
Thanks. That did work but now the decision tree has the same error. It says;
"Missing a start node or end node"
The decision tree is between the start group and end group.
Any advise on this please?
Thanks

Your suggestion worked!
Thank you so much.
Much appreciated.
