Consistency of Regression Analysis for High-dimensional Data
Abstract :The methods of linear regression analysis for high-dimensional data generally includes the following methods: LASSO, LASSO-type, SCAD. The first chapter of this paper introduces LASSO, focusing on the bridge regression, adaptive LASSO, and SCAD. The second part explains the consistency of adaptive LASSO and bridge regression in linear regression models. In addition, the third part describes the consistency of SCAD in general linear regression models. In the last, the statistical challenges with high dimensionality are discussed.
Keywords:Bridge regression; LASSO; SCAD; Consistency
