主 题:Spline LASSO in high-dimensional linear regression
内容简介:A Spline-LASSO approach is proposed for a high-dimensional linear regression problem, where the covariates are ordered in a meaningful way. It is designed to tackle the case where the shape of the parameter values changes smoothly, whereas fused Lasso is better fitted for piecewise constant functions. Computationally it can be easily modified to use LARS algorithms. Simulations and real example will be given.
