Description: Implements covariance-stabilised sufficient dimension reduction
 for continuous responses, with an additional sparse engine for continuous,
 categorical, and right-censored survival responses and information-theoretic
 structural dimension
 selection. Supported methods include sliced inverse regression, sliced
 average variance estimation, directional regression, and principal Hessian
 directions. Sample, ridge, Oracle Approximating Shrinkage, Ledoit-Wolf, and
 Maximum Entropy Covariance (MEC) estimators are provided alongside
 prediction, resampling, simulation, and diagnostic utilities. The
 sufficient dimension reduction
 methods build on Li (1991) <doi:10.1080/01621459.1991.10475035>, Li (1992)
 <doi:10.1080/01621459.1992.10476258>, and Li and Wang (2007)
 <doi:10.1198/016214507000000536>. Covariance shrinkage follows Olorede and
 Yahya (2019) <doi:10.48550/arXiv.1909.13017>, Ledoit and
 Wolf (2004) <doi:10.1016/S0047-259X(03)00096-4> and Chen et al. (2010)
 <doi:10.1109/TSP.2010.2053029>.
