Huber regression (HR) is a popular robust alternative to the least squares regression when the error follows a heavy-tailed distribution. We propose a new method called the enveloped Huber regression (EHR) by considering the envelope assumption that there exists some subspace of the predictors that has no association with the response, which is referred to as the immaterial part. More efficient estimation is achieved via the removal of the immaterial part. Different from the envelope least…

Partial Envelopes for Efficient Estimation in Multivariate Linear Regression
We introduce the partial envelope model, which leads to a par simonious method for multivariate linear regression when some of the predictors are of special interest. It has the potential to achieve
A Bayesian approach for envelope models
TLDR
A comprehensive Bayesian framework for estimation and model selection in envelope models in the context of multivariate linear regression is developed and can accommodate situations where the sample size is smaller than the number of responses.

TLDR
A novel, sufficient optimality condition that relies on a convex differencing representation of the penalized loss function and the subdifferential calculus is introduced that enables the oracle property for sparse quantile regression in the ultra-high dimension under relaxed conditions.
