%description
Provides comprehensive tools for blinded sample size re-estimation (BSSR)
in two-arm clinical trials with binary endpoints. Unlike traditional
fixed-sample designs, BSSR allows adaptive sample size adjustments during
trials while maintaining statistical integrity and study blinding.
Implements five exact statistical tests: Pearson chi-squared, Fisher
exact, Fisher mid-p, Z-pooled exact unconditional, and Boschloo exact
unconditional tests. Supports restricted, unrestricted, and weighted BSSR
approaches with exact Type I error control. Statistical methods based on
Mehrotra et al. (2003) <doi:10.1111/1541-0420.00051> and Kieser (2020)
<doi:10.1007/978-3-030-49528-2_21>.
