msaenet

msaenet implements the multi-step adaptive elastic-net (MSAENet) algorithm for feature selection in high-dimensional regressions proposed in Xiao and Xu (2015) [PDF].

Nonconvex multi-step adaptive estimations based on MCP-net or SCAD-net are also supported.

Check vignette("msaenet") to get started.

Installation

You can install msaenet from CRAN:

install.packages("msaenet")

Or try the development version on GitHub:

remotes::install_github("nanxstats/msaenet")
