Dear All,

I have a process flow with ( NN ,Decision tree , MBR and Gradient Boosting) and model comparison node to compare the results.

I need to draw the ROC for models. Can I get helping?

In the results of model comparisons, I get the results of ROC in output, But I need to draw the curve.

Thanks

You need a binary target for a ROC curve.

ROC curve (the graph) is also there in the results window of model comparision node. It is desplayed by default. But if for some reason it is not visible, search it in the View menu.

When I open the results of model comparison, I coludn't find it.

Can you have any method to enable the roc ?

It should be there. What is in the View menu? What tables, graphs, outputs do you see?

Do you have a binary target variable?

The target is multiclass not binary and the view menu includes (outputs , fit statistics ,score ranking overlay)

thanks

The View Menu includes ( output , fit statistics and score ranking overlay). The model is multitarget and the model selection is ROC and selection table is Test dataset.

My E-Miner version is 6.2.

Thanks
