Probability for rank:pairwise

#1

Hi ,

I am using R api for xgboost. I would like to know whether the predict for rank:pairwise can give probability as output.

Thanks,
Eric

No, it cannot. The prediction will only give you relative ordering between rows.

Thank you for the feedback. Would it be meaningful if I fit another ranking model such as rank order logit using the prediction score output by rank:pairwise as covariant to get the probability ?

Perhaps. I have no idea.
