Hello

 

Was wondering if anyone has any suggestions to why the precision and recall curves, and ROC curve not displaying in the R anchor of the cross validation tool? see the below screenshots. The lift and gain plots are successfully displaying.

It's to do with the low AUC scores which makes it hard to plot (I think), given the high F1 score you have a great model

Dropped a few predictor variables and got a graph

I did think it was strange that the average AUC was so low given how hight he accuracy and F1 scores are. usually this can happen when the dataset is unbalanced with the target classes which isnt the case here. Interestingly I tried the model comparisont tool and it outputed the required plots and congruent AUC score.

Oh wow look at that. Seemed to fix it for me too - handy to know for the future. Many thanks @aatalai
