AUC / ROC for presence only.
Dear all,
I have a probability of presence of distribution of a species of interest
(varying from 0 to 1 in continuous form) and I have a set of points
where I know that species really occurs. But I donĀ“t have points of absence.
So, for each true presence I know the estimated presence.
I would like to know how can I compute AUC, taking account these
Available data.
Best wishes,
