Decision Tree: same variable more than once in the branch?!
Posted by TheTechie at 5/31/2006 1:24:03 PM
I was surprized when SQL Server 2005 produced a desision tree with one branch
referring to the same variable at more than one level.
E.g it produced branches like these:
All--A>100--B>10--A>120
All--A>100--B>10--A=<120
All--A>=100--B<=10
All--A<100
