Hello list,
I am trying to perform ROC analysis and count the AUC in order to validate
my results. I use package ROCR. I would like to count the AUC not under the
cutoff found by "performance" but to use another cutoff that I calculate.
How could I change the following command in order to get what I want?
perform=performance(pred,measure="auc",x.measure="cutoff"), where pred is a
prediction object.
Thank you very much,
Eleni
