New statistical methods tackle covariate shift in model testing · 1 source tracked

Researchers have developed new methods for nonparametric goodness-of-fit testing when data distributions differ between source and target populations. The approach uses truncated importance-weighting kernel ridge regression combined with a multiplier bootstrap to create confidence sets for regression functions. This technique is robust even with heavy-tailed density ratios and is validated by theoretical proofs and numerical experiments. AI

    Nonparametric Goodness-of-fit Testing under Covariate Shift

    arXiv:2608.04860v1 Announce Type: cross Abstract: This paper develops procedures for nonparametric goodness-of-fit testing under covariate shift, where labelled data are drawn from a source population but goodness-of-fit is evaluated for a target population. The distribution mism…
