Running Model Comparison Node on a Model from R

N595 — Fri, 04 Aug 2017 13:53:38 GMT

I'm trying to run a model comparison node in Enterprise Miner to compare the accuracy of two models, one of which was made in Miner, the other in R. I've tried to import a data source containing the actuals and predictions made by R into Enterprise Miner, then manually setting the roles to prediction and target but I'm getting an error message saying the model comparison node "must use one target variable modeled by a predecessor node". Is there an easy way to get SAS to treat the prediction from my R model as if it had been generated in SAS?

Thanks.

Hi there, just checking that you are using the Model Import node to import your model following the Input Data node?

No, I wasn't using a Model Import node but that seems to have fixed the problem - thanks!
