selSurv: Inference after Cox-Lasso Variable Selection

Methods for inference after Cox-Lasso variable selection in right-censored survival data. The package provides Cox-Lasso fitting, support-restricted Cox refitting, sample splitting, approximately debiased coefficient estimates, score-level bootstrap intervals, and model-based bootstrap intervals with fixed-support or repeated-selection procedures. The methods differ in their inferential targets and theoretical guarantees. Relevant methodological investigations are presented in Schemet and Friedrich-Welz (2026) <doi:10.1186/s12874-026-02887-0>, Schemet, Groll and Friedrich-Welz (2026) <doi:10.48550/arXiv.2608.18893>, and Schemet and Friedrich-Welz (2026) <doi:10.48550/arXiv.2608.24230>.
