In regression models, the phenomenon of the correlated noise is called endogeneity, which is due to unobserved variables and others, and has been a major problem setting in causal inference and …
Web30 de jun. de 2024 · Abstract. Variable selection and parameter estimation are fundamental and important problems in high dimensional data analysis. In this paper, … 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.
