Cutoff range of values starts with Inf

[olapuentesantana]

Hi there,

After running ROCR::prediction(), I see the range of cutoff values automatically defined starts with Inf:

pred@cutoffs[[1]]
[1] Inf  41.40679819  36.37975270  35.71213388  30.26013347 24.41121159  ....

Could you please explain if this is a bug or if this is the expected behaviour? Thank you, Óscar

Hi Oscar,

sorry for the very delayed reply. The answer to your question very much depends on your input data. However, I would offer a guess and think this is expected. The largest cutoff is Inf meaning "no cut off". Does this make sense to you?

Best
