Good afternoon,
I am struggling to interpret the results of the decision tree diagram (see attachment 1) as I cannot display the original labels of the categories contained in each leaf, which have been substituted by numbers indicating each different level. Needless to say that I have explored all options available both on the menu on the top and by right clicking and checking Graph properties / View / Tools / etc.
This also applies when I open the distributions of nominal variables (e.g.Product Name) by right-clicking on the "File-Import" node (see attachment 2).
I used to do this quite rapidly from SAS -> Solution -> Analysis -> EM, but now I have a different license and cannot run SAS EM from SAS, so I can only use SAS EM 12.3 which is a different software.
Any help greatly appreciated,

Hi.
So you want the formatted values to show up as node labels instead of the raw integers, right?
Does it work if you use the DM Exa -1 sample dataset? The dataset includes several formatted numeric inputs like edlevel, marital. When I treat them as nominal and build the tree, I see the formatted values. See attachment.
Is it possible that options nofmterr is in effect so your dataset is being loaded without the formats?
Hope this helps.

why there is always "or Missing" in the labels, though i have no missing values in data? isn't it annoying? is there anyway to not to show on the tree? thanks!
