Researchers have developed a new robust regression method that addresses challenges posed by heavy-tailed noise and outliers in high-dimensional data. This approach utilizes a non-smooth Wilcoxon score-based rank objective and incorporates group sparsity regularization. The method includes a simulation-based tuning rule and establishes a finite-sample error bound for its estimator, demonstrating effectiveness and robustness in numerical experiments. AI
