smsncut 0.1.0 (2026-05-19)
- Initial release on CRAN.
- Core SMSN distribution functions:
smsn_fit, smsn_density, smsn_cdf,
smsn_quantile, smsn_rdist.
- Decision-theoretic cutoff:
cutoff_optimal, cutoff_youden, cutoff_risk,
cutoff_phi.
- Asymptotic inference:
cutoff_variance, cutoff_ci, cutoff_identifiability.
- Admissible interval tools:
cutoff_admissible_interval, cutoff_boundary_check,
cutoff_build_interval, cutoff_expand_interval_until_valid.
- ROC analysis:
smsn_roc, smsn_auc.
- Monte Carlo simulation:
mc_one_rep, mc_simulate_scenario, mc_run_all.
smsn_fit uses Richardson extrapolation (numDeriv::hessian) for the
observed Fisher information matrix, critical for accurate variance estimation.- Implements the methodology of de Paula, Mouriño, and Dias Domingues (2026),
