"how to read the event count in decision tree"

happydust

Hi Guys:
i am new to Rapidmnier, and i have a question:
for the decision trees, once i got a treeModel, is there a way i can read the event count? (on the leave node, like how many cases are predicted in this node)

Thanks!

best

Hi,
this is either shown in the Text View of the model or by a tool tip if you position the mouse over the tree view.

Thanks!
However, what i am doing now, is doing a JAVA application, so i want to be able to read the count from java-- meaning in the code instead of going to rapidminer and find the count manually . Do you know how to do that?

Really appreciate your help!

Hi,
of course, I wrote the thing at least partially. I would suggest taking a look at the Java Doc of the TreeNode. You will find a suitable method there.
