AWhat changed
Weights conformity-score quantiles by test-to-training covariate likelihood ratios, extending prediction coverage to a covariate-shift and weighted-exchangeability setting.
Scientific scope
Weights conformity-score quantiles by test-to-training covariate likelihood ratios, extending prediction coverage to a covariate-shift and weighted-exchangeability setting. Exact theorem requires unchanged conditionalY|X, absolute continuity and correct density-ratio weights; estimated ratios do not inherit exact validity automatically. Not arbitrary concept/label shift or pointwise conditional coverage. Existing conformal and importance weighting are inherited.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
