%description
Extremely efficient toolkit for solving the best subset selection problem
<https://www.jmlr.org/papers/v23/21-1060.html>. This package is its R
interface. The package implements and generalizes algorithms designed in
<doi:10.1073/pnas.2014241117> that exploits a novel
sequencing-and-splicing technique to guarantee exact support recovery and
globally optimal solution in polynomial times for linear model. It also
supports best subset selection for logistic regression, Poisson
regression, Cox proportional hazard model, Gamma regression,
multiple-response regression, multinomial logistic regression, ordinal
regression, (sequential) principal component analysis, and robust
principal component analysis. The other valuable features such as the best
subset of group selection <doi:10.1287/ijoc.2022.1241> and sure
independence screening <doi:10.1111/j.1467-9868.2008.00674.x> are also
provided.
