WebFor example, if Y is predicted with three variables X 1, X 2, and X 3, where X 1 is the single most predictive model, but X 2 and X 3 together is the best model, neither forward nor backward step-wise selection will choose that model. Penalized regression can perform variable selection and prediction in a "Big Data" environment more effectively ... 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.
