SPSS Classification Tree Tutorial - Credit Rating using tree_credit.sav.
The 1st 3 nodes are based on Income. The splitting criteria for each node is
-
Diagramme Labels
Node 1 - <=Low
Node 2 - Low,Medium
Node 3 - > Medium
If one looks at the sample sizes in both the Chaid analysis & the data then
Node 1 = 553 = Low Income
Node 2 = 1134 = Medium
Node 3 = 777 = High
Why isn't the diagramme labelled as
Low instead of <=Low
Medium instead of Low,Medium
High instead of > Medium ?
Can anyone explain this ?
Regards
