decision tree output - only first table showing - not getting any branch or split from first table

[VISHALKAPASI]

Hello Everyone..

Well, I was running Decision Tree in SAS Eminer 12.1 version, and initially 2-3 times I get output of Decision tree as well.

But, after few hours I re-run the decision tree on same data, I have got only 1 output (Total observation with Target flag 1 and 0 and % of total observations) . So I have tried to learn from the log but I could not understand.

If you could help to resolve this issue (from below log), it would be great.

NOTE: Fileref _FDSEP has been deassigned.

Thank you in advance..

Vishal,

In this case, the portion of the log doesn't give enough information to determine the reason for the tree returning no splits.  Please go to the following URL and create a track with Technical Support.  They will be able to help resolve this issue.  The URL is:
