WebOne common assumption for high-dimensional linear regression is that the vector of regression coefficients is sparse, in the sense that most coordinates of are zero. Many statistical procedures, including the Lasso, have been proposed to fit high-dimensional linear models under such sparsity assumptions. WebTheoretical guarantees for VB in sparse linear regression have recently been obtained in [38]. We combine ideas from this paper with tools from high-dimensional and …
