%description
Implements propensity score weighting methods for estimating
counterfactual survival functions, marginal hazard ratios, and weighted
Kaplan-Meier and cumulative risk curves in observational studies with
time-to-event outcomes. Supports binary and multiple treatment groups with
inverse probability of treatment weighting (IPW), overlap weighting (OW),
and average treatment effect on the treated (ATT). Includes symmetric
trimming (Crump extension) for extreme propensity scores. Variance
estimation via analytical M-estimation or bootstrap. Methods based on Li
et al. (2018) <doi:10.1080/01621459.2016.1260466>, Li & Li (2019)
<doi:10.1214/19-AOAS1282>, and Cheng et al. (2022)
