msaenet

msaenet implements the multi-step adaptive elastic-net (MSAENet) algorithm for feature selection in high-dimensional regressions proposed in Xiao and Xu (2015) <DOI:10.1080/00949655.2015.1016944> (PDF).

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