⚠️There's a newer version (1.2-22) of this package.Take me there.

lasso2 (version 1.2-19)

L1 constrained estimation aka `lasso'

Description

Routines and documentation for solving regression problems while imposing an L1 constraint on the estimates, based on the algorithm of Osborne et al. (1998)
