I have posted a "similar" question in another thread. But I think that question is not specific/concrete enough to get the answer I expected.
I know that, in survival analysis, the concordance index (c-index) can be used to measure how well a ranking list is w.r.t survival times of subjects (F. E. Harrell, 1996, section 5.5). That is, if subjects with higher survival times get higher scores from the model, the c-index of the model will be large.
My question is: can the score be interpreted as the risk of the subject? In other words, do subjects with smaller scores (which indicates shorter survival times) correspond to larger failure risk?
