WebSep 1, 2024 · Variable Selection with Second-Generation P-ValuesYi Zuo, PhDVanderbilt University. Many statistical methods have been proposed for variable selection in the past century, but few balance inference and prediction tasks well. Here, we report on a novel variable selection approach called penalized regression with second-generation p-values ... WebSubset selection is unbiased but computationally costly. The MC+ has two elements: a minimax concave penalty (MCP) and a penalized linear unbiased selection (PLUS) …
WebThe optimality of the MC+ is proved in the sense that the amount information it requires for consistent variable selection in the linear regression model is of the same order as the minimum possible under mild conditions on deterministic or random design matrices. We prove the optimality of the MC+ [16] in the sense that the amount information it requires … WebSCAD can yield consistent variable selection in large samples (Fan and Li(2001)). MC+ has two components: a minimax concave penalty (MCP) and a penalized linear unbiased …
WebJul 2, 2024 · Subset selection is unbiased but computationally costly. The MC+ has two elements: a minimax concave penalty (MCP) and a penalized linear unbiased selection (PLUS) algorithm. The MCP provides the convexity of the penalized loss in sparse regions to the greatest extent given certain thresholds for variable selection and unbiasedness. WebSCAD can yield consistent variable selection in large samples (Fan and Li(2001)). MC+ has two components: a minimax concave penalty (MCP) and a penalized linear unbiased selection (PLUS) algorithm (Zhang et al.(2010)). MC+ returns a continuous piecewise linear path for each coe cient as the penalty increases from zero (least squares) to in nity
WebIn the third part, we develop a generalized penalized linear unbiased selection (GPLUS) algorithm to compute the solution paths of concave-penalized negative log-likelihood for generalized linear model. We implement the smoothly clipped absolute deviation (SCAD) and minimax concave (MC) penalties in our simulation study to demonstrate the ...
