%description
Provides methods for linear regression in the presence of missing data,
including missingness in covariates and responses. The package implements
two estimators: oss_estimator(), a low-dimensional semi-supervised method,
and dantzig_missing(), a high-dimensional approach. The tuning parameter
can be selected automatically via cv_dantzig_missing(). See Risebrow and
Berrett (2026) <doi:10.48550/arXiv.2602.13729>. Optional support for the
'gurobi' optimizer via the 'gurobi' R package (available from Gurobi, see
<https://docs.gurobi.com/projects/optimizer/en/current/reference/r.html>).
