Combines propensity scores and prognostic scores with\nsurvey design weights for matching, survey-weighted imputation\nwithin match sets, and Hajek normalization to target the\npopulation average treatment effect (PATE) and the population\naverage treatment effect on the treated (PATT). Supports both\nretrospective (treatment-dependent) and prospective\n(treatment-independent) sampling designs. Achieves double\nrobustness: consistent estimation when either the propensity\nscore or prognostic score model is correctly specified.\nProvides polynomial sieve bias correction and\nlinearization-based multinomial bootstrap variance estimation\nthat preserves the survey-weighted matching structure without\nre-matching. Methods are described in Zeng, Tong, Tong, Lu,\nMukherjee, and Li (2026, under review) \"Where to weight?\nEstimating population causal effects with weighted double score\nmatching in complex surveys\".", "License": "GPL-3", "Encoding": "UTF-8", "LazyData": "true", "RoxygenNote": "7.3.2", "Config/testthat/edition": "3", "URL": "https://github.com/ykzeng-yale/wdsmatch", "BugReports":
