SAS Enterprise Miner 14.3: Is it possible to obtain an ROC curve from score data?

mzhao — Mon, 07 Oct 2019 19:02:54 GMT

Hi SAS community,

From the model comparison node, I was only able to obtain ROC curves from the training, validation, and test data (from the data partitions of the training data set). I want to obtain an ROC curve from the score data. Is this possible? If it is, then how do we do it?

Thanks

Hello,

see here:

To plot everything (the ROC curves) in the Results pane of your SAS Code Node, see this tip:

In the score data, you typically do not have an observed target, so you wouldn't be able to create an ROC curve for that.
