High-dimensional data bootstrap

Web23 de jun. de 2024 · This paper considers a new bootstrap procedure to estimate the distribution of high-dimensional ℓ_p-statistics, i.e. the ℓ_p-norms of the sum of n independent d-dimensional random vectors with d ≫ n and p ∈ [1, ∞]. We provide a non-asymptotic characterization of the sampling distribution of ℓ_p-statistics based on … Web21 de ago. de 2024 · The parameter \(\gamma \) controls the concavity in both SCAD and MCP penalties: small values of \(\gamma \) indicate that the penalty tends to be concave. It is interesting to note also that when \(\gamma \rightarrow \infty \) both SCAD and MCP reduce to the LASSO penalty.. 2.2 Group Variable Selection. In high dimensional …
