Enterprise Miner Tree Model Failure with Character Ordinals
I was running a tree model in Enterprise Miner with standard defaults. I
had some character variables enter the model. They had been classified as
nominal, but should have been ordinal, so I reclassified them as ordinal
in a data set attributes node, and ran a new tree on the modified data.
Now, the tree fails unless I remove those variables from the model. The
failure always occurs in PROC SPLIT as a "SPLIT internal error. Should
not happen." Then it gives some traceback information and says "Read
Access Violation in Task ( SASDSVX ] Exception occurred at (67E6D9C8) Task
Has anyone here run into something similar? As I alluded above, it
appears to be related to ordinalizing character variables. The tree model
will run fine if I exclude the ordinal variables, and it ran fine before I
changed their attributes from nominal to ordinal.
