I have 2 non-nested models that I would like to compare with respect to their predictive accuracy (concordance index). I have used Harrell's (Efron-Gong) bootstrap-based optimism-correction internal validation procedure to derive optimism-corrected C-indices for the 2 models. How do I compare these 2 optimism-corrected C-indices to see which model is better, i.e. how to perform a statistical test to determine which is significantly better than the other?
