Researchers have developed a new non-parametric method for estimating conditional distributions, which can be used for conformal regression. This approach involves partitioning data into bins and using the empirical cumulative distribution function within each bin to predict distributions. The method optimizes bin boundaries by minimizing a leave-one-out Continuous Ranked Probability Score (LOO-CRPS) and selects the optimal number of bins through cross-validation. The resulting prediction bands and sets offer finite-sample coverage guarantees and demonstrate narrower intervals than existing split-conformal methods on benchmark datasets. AI
