Fusing regression coefficients into homogenous groups can unveil those coefficients that share a common value within each group.

Method of Contraction-Expansion (MOCE) for Simultaneous Inference in Linear Models

no code implementations4 Aug 2019 Fei Wang, Ling Zhou, Lu Tang, Peter X. -K. Song

To establish a simultaneous post-model selection inference, we propose a method of contraction and expansion (MOCE) along the line of debiasing estimation that enables us to balance the bias-and-variance trade-off so that the super-sparsity assumption may be relaxed.
