What should I do for checking ROC curve when I use bagging algorithm ?

[zhddhkdn]

Hi,
I want to check ROC curve when I use bagging algorithm.

(This is a column rename for ROC curve)
I can select ‘P (risk=good)’ for using cross validation.
But there is no ‘P (risk=good)’ when I use bagging algorithm.

Please tell me how to see ROC curve of bagging results and the reason why ‘P (risk=good)’ is hidden.

Thank you.

Hi @zhddhkdn and welcome to the forum.

It’s hard to know for sure without seeing your workflow, but my best guess is this: in the predictor node for your workflow, make sure to check the box to append columns with normalized class distribution (note that this option has slightly different names depending on the algorithm you’re using).

If that’s no help, please post an example workflow so that we can investigate further.
