%description
Implements statistical methods for exploratory subgroup identification in
clinical trials. Provides tools for identifying patient subgroups with
differential treatment effects using machine learning approaches including
Generalized Random Forests (GRF), LASSO regularization, and exhaustive
combinatorial search algorithms. Supports survival endpoints (Cox
proportional hazards), binary outcomes (log odds ratio, log relative risk,
risk difference), continuous outcomes (mean difference), and count / rate
outcomes (log incidence rate ratio via Poisson, quasi-Poisson, or
negative-binomial GLMs with optional person-time offset). Features
bootstrap bias correction using infinitesimal jackknife methods to address
selection bias in post-hoc analyses. Designed for clinical researchers
conducting exploratory subgroup analyses in randomized controlled trials,
particularly for multi-regional clinical trials (MRCT) requiring regional
consistency evaluation. Methods are described in Leon et al. (2024)
<doi:10.1002/sim.10163>. Post-selection inference for the identified
subgroup follows León and Anderson (2026) <doi:10.48550/arXiv.2609.38361>.
