A Parallel Algorithm for Large-Scale Nonconvex Penalized Quantile Regression Autor Yu, Liqun, Lin, Nan, Wang, Lan

“… This results in a new single-loop algorithm, which we refer to as the QPADM algorithm. The QPADM demonstrates favorable performance in both computational speed and statistical accuracy, particularly when the sample size n and/or the number of features p are large. Supplementary material for this article is available online…”
