Hi,
I am doing an experiment with cancer data where I want to evaluate the perf=
ormance of a model on various stages of cancer that are present in the data=
set.
Consequently after crossvalidating I want to go over the predictions and gr=
oup them by cancer stage so I can calculate various statistics for each can=
cer stage.
However, after I run eval.crossValidateModel() I no longer know which predi=
ction belongs to which Instance in the dataset.
Since Eval.predictions() does not provide any usefull identifiers to match =
it back to the instances, I originally assumed the prediction would maintai=
n the same order as the instances in the dataset, but this is not correct.
How do I determine which prediction belongs to which records?
Many thanks in advance,
Regards,
Florian
