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
