R package for Lasso and Elastic net penalty
Post date: Jul 8, 2013 7:13:57 AM
I always use this R package from Stanford's stats group.
http://cran.r-project.org/web/packages/glmnet/index.html
The package is used accompanied with this paper:
http://www.jstatsoft.org/v33/i01/paper
The package implemented all those equations in the paper.
Example codes can be found in the help came with the package.
I should provide my own example code when I have time.
