High-dimensional data bootstrap
Web10 de dez. de 2024 · We carry out a numerical study of the spinless modular bootstrap for conformal field theories with current algebra U(1)c × U(1)c, or equivalently the linear programming bound for sphere packing in 2c dimensions. We give a more detailed picture of the behavior for finite c than was previously available, and we extrapolate as c → ∞. Our … 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 …

Web18 de mar. de 2024 · High-dimensional covariance matrix estimation plays a central role in multivariate statistical analysis. It is well-known that the sample covariance matrix is singular when the sample size is smaller than the dimension of the variable, but the covariance estimate must be positive-definite. This motivates some modifications of the sample …
