Calibration curve

Hello, I would like to know if it is possible in KNIME to calculate the Brier score for a prediction model. That is, the calibration curve (the observed ratio of an event versus the expected ratio of the event) for a prediction model. Also assessed using Hosmer-Lemeshow goodness of fit statistics.
Thank you.

Hi @datascience100,

We don’t have a dedicated node to compute the Brier score. But you can use the One to Many node to generate a one-hot encoding of the observed class and then use a Math Formula node to compute the score for each prediction.

Best regards,
