Description: Implements weighted double score matching (WDSM) for
        estimating population-level causal effects from complex survey
        data. Combines propensity scores and prognostic scores with
        survey design weights for matching, survey-weighted imputation
        within match sets, and Hajek normalization to target the
        population average treatment effect (PATE) and the population
        average treatment effect on the treated (PATT). Supports both
        retrospective (treatment-dependent) and prospective
        (treatment-independent) sampling designs. Achieves double
        robustness: consistent estimation when either the propensity
        score or prognostic score model is correctly specified.
        Provides polynomial sieve bias correction and
        linearization-based multinomial bootstrap variance estimation
        that preserves the survey-weighted matching structure without
        re-matching. Methods are described in Zeng, Tong, Tong, Lu,
        Mukherjee, and Li (2026, under review) "Where to weight?
        Estimating population causal effects with weighted double score
        matching in complex surveys".
