| Abstract: |
| This paper studies the problem of variable selection and parameter estimation
in high-dimensional linear models,
presents a generalized SELO penalty function family
and extends the SELO-penalized regression method to a more general framework.
Simulation studies and a real data analysis are conducted to assess the finite sample performance of the proposed method. |
| Key words: coordinate descent high-dimensional BIC local linear approximation penalized least squares SELO penalty |
