Statistics on pairs
Read OriginalThe article delves into technical statistical methods for complex, structured data samples (clustered, longitudinal, network). It focuses on the relationship between design-weighted U-statistics (sums over observation pairs) and their Hoeffding projections (sums over single observations), examining when weighting should be applied. It uses the variance and the Wilcoxon-Mann-Whitney test as examples to build intuition for estimators in sampling designs.
