%description
Implements causal inference methods for incorporating external control
data into randomized controlled trials (RCTs) with longitudinal outcomes.
Provides an analysis module supporting weighting-based methods such as
inverse probability weighting (IPW) and augmented inverse probability
weighting (AIPW), difference-in-differences (DID), and synthetic control
approaches for borrowing external control information, as well as a
simulation module for generating trial and external control data,
evaluating estimator performance via Monte Carlo studies, and conducting
power analyses for sample size determination. Methods are based on Zhou et
al. (2025) <doi:10.1093/jrsssa/qnae075> and Zhou et al. (2024)
<doi:10.1080/10543406.2024.2330209>.
