Hi

How one can calculate the Matthews correlation coefficient (MCC) pefromance for a specific pridector?

Hi Malik,

this should be possible by using the Scorer node followed by the Math Formula-node where you can directly insert the MMC-formula (based on the FPs, FNs, etc. provided by the Scorer's second output port).

Cheers,

Martin

Dear Martin

Thanks so much. It works fine. 

How i can add to the table of the performance the value of ROC curve?

(TruePositives    FalsePositives    TrueNegatives    FalseNegatives    Recall    Precision    Sensitivity    Specifity    F-measure...)

 

Thanks

Malik

Run the ROC node and then join (joiner node) the output. If it's a binary model you have you can use the Binary Scorer node to get a single row output for the performance of the model.
