Similar to AUC in regression. Evaluate values for distributed differences, not accuracy.
As an example, if the IC50 value for drug A and B is each 30 and 40, the predicted value for A should be lower than B.
It is a value of whether there is a significant distributional difference with the ranking information.
(often used in clinical data.)
(Lifelines provides more extended functions, so it would be a good idea to consider that.)
