LASSO is a very useful variable selection method for high-dimensional data, But it does not possess oracle property[Fan and Li, 2001] and group effect[Zou and Hastie, 2005]. In this paper, we firstly review four improved LASSO-type methods which satisfy oracle property and(or) group effect, and then give another two new ones called WFEN and WFAEN. The performance on both the simulation and real data sets shows that WFEN and WFAEN are competitive with other LASSO-type methods.
