Can elastic net do binary classification?
Hi, List
The elastic net package (by Hastie and Zou at Stanford) is used to do
regularization and variable selection, it can also do regression. I am
wondering if it can perform binary classification (discrete outcome).
Anybody having similar experience?
Many thanks,
-Jack

R-help Digest, Vol 67, Issue 23
...better option might be this: Trevor Hastie and a student of his have
recently put out a paper that does a step-up from penalized discriminant
analysis based, I think, on Trevor's sparse principal component analysis
method (in his elasticnet package).

You can get R-code to do the analysis on the first author's website; there's
a link in the paper.
Bye, Mark.
