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".
