Get the Most out of Your Sample: Optimal Unbiased Estimators using Partial Information
Summary: Method to derive optimal unbiased estimators for multi-instance queries (quantiles, ranges, subset-sums) that exploit partial information across sampled instances, improving on per-instance Horvitz–Thompson. Prove variance optimality and show large empirical gains. (summarized by gpt-5-mini on Feb 09 2026)
