%description
An implementation of best subset selection in generalized linear model and
Cox proportional hazard model via the primal dual active set algorithm
proposed by Wen, C., Zhang, A., Quan, S. and Wang, X. (2020)
<doi:10.18637/jss.v094.i04>. The algorithm formulates coefficient
parameters and residuals as primal and dual variables and utilizes
efficient active set selection strategies based on the complementarity of
the primal and dual variables.
