Hi everyone ,
I was wondering if the creation of dummy variable for the node regression was an automatical process.
I know it create k-1 modalities interval modalities for a nominal variable which has k modalities
It's an automatic process ?
Thank for this confirmation
Yes, the procedures used for regression in EM all internally/automatically create dummy variables for class inputs.

Thank you Wendy for this clarification.
Is there a reference point in a SAS manual so I can see how it is doing this 'internally/automatically' to ensure it is doing what I expect?
Thank you!! Rod.
