WebAn alternative is a smoothed bootstrap. We begin by tting a kernel density to the original data then draw random simulated observations from this distribution. Faced with original values between 20:58 and 03:14, most simulated observations would fall in the same range, but a few will fall outside. http://papers.neurips.cc/paper/3404-on-bootstrapping-the-roc-curve.pdf
