Web11 de fev. de 2024 · During the revision of our paper, we learned that a recent work ( Vaskevicius et al., 2024) also studied high-dimensional linear regression via implicit regularization via a slightly different parameterization. Our work is different from Vaskevicius et al. (2024) in many aspects. A detailed comparison between the two works is provided … Weblibrary ncvreg (version 3.9.1) for nonconvex regularized sparse regression, the most popular Rlibrary glmnet (version 2.0-13) for convex regularized sparse regression, and two Rlibraries scalreg-v1.0 and flare-v1.5.0 for scaled sparse linear regression. All experiments are evaluated on an Intel Core CPU i7-7700k 4.20GHz and under R version 3.4.3.
WebIn this work, we incorporate matrix projections into the reduced rank regression method, and then develop reduced rank regression estimators based on random projection and orthogonal projection in high-dimensional multivariate linear regression model. We propose a consistent estimator of the rank of the coefficient matrix and achieve … Webin: (1) Wainwright [27], which tackles the problem of high-dimensional sparse linear regression with Gaussian noise, and (2) Daskalakis et al. [9], which tackles the problem of truncated linear regression. The tools developed in those papers do not suffice to solve our problem, since each difficulty interferes with the other.

WebWe propose two variable selection methods in multivariate linear regression with high-dimensional covariates. The first method uses a multiple correlation coefficient to fast reduce the dimension of the relevant predictors to a moderate or low level. The second method extends the univariate forward regression of Wang [ (2009).
